A highly ordered nanostructured carbon–sulphur cathode for lithium–sulphur batteriesXiulei Ji,Kyu Tae Lee and Linda F.Nazar *The Li–S battery has been under intense scrutiny for over two decades,as it offers the possibility of high gravimetric capacities and theoretical energy densities ranging up to a factor of five beyond conventional Li-ion systems.Herein,we report the feasibility to approach such capacities by creating highly ordered interwoven composites.The conductive mesoporous carbon framework precisely constrains sulphur nanofiller growth within its channels and generates essential electrical contact to the insulating sulphur.The structure provides access to Li +ingress/egress for reactivity with the sulphur,and we speculate that the kinetic inhibition to diffusion within the framework and the sorption properties of the carbon aid in trapping the polysulphides formed during redox.Polymer modification of the carbon surface further provides a chemical gradient that retards diffusion of these large anions out of the electrode,thus facilitating more complete reaction.Reversible capacities up to 1,320mA h g −1are attained.The assembly process is simple and broadly applicable,conceptually providing new opportunities for materials scientists for tailored design that can be extended to many different electrode materials.Safe,low-cost,high-energy-density and long-lasting recharge-able batteries are in high demand to address pressing environmental needs for energy storage systems that can be coupled to renewable sources 1,2.These include wind,wave and solar energy,as well as regenerative braking from vehicular transport.With production of oil predicted to decline,and the number of vehicles and their pollution impact increasing globally,a transformation in transportation economy is inevitable given that we live in a carbon-constrained world.One of the most promising candidates for storage devices is the lithium–sulphur cell.Under intense scrutiny for well over two decades,the cell in its simplest configuration consists of sulphur as the positive electrode and lithium as the negative electrode 3,4.It differs from conventional lithium-ion cells,which operate on the basis of topotactic inter-calation reactions:reversible uptake of Li ions and electrons in a solid with minimal change to the structure.They typically use a lithium transition-metal oxide or phosphate as a positive electrode (cathode)that de/re-intercalates Li +at a high potential with respect to the carbon negative electrode (anode).As the reaction is topotac-tic at both electrodes,the charge storage capability is inherently limited to about 300mA h g −1for any prospective system,and maximum capacities observed so far are 180mA h g −1with high power characteristics having been reported 5.The lithium–sulphur cell operates quite differently.The redox couple,described by the reaction S 8+16Li ↔8Li 2S lies near 2.2V with respect to Li +/Li o ,a potential about 2/3of that exhibited by conventional positive electrodes 6.However,this is offset by the very high theoretical capacity afforded by the non-topotactic ‘assimilation’process,of 1,675mA h g −1.Thus,compared with intercalation batteries,Li–S cells have the opportunity to provide a significantly higher energy density (a product of capacity and voltage).Values can approach 2,500W h kg −1or 2,800W h l −1on a weight or volume basis respec-tively,assuming complete reaction to Li 2S (refs 7,8).Despite its considerable advantages,the Li–S cell is plagued with problems that have hindered its widespread practical realization.These arise from the fact that all components of the cell must be addressed as a whole,including the interfaces betweenUniversity of Waterloo,Department of Chemistry,Waterloo,Ontario N2L 3G1,Canada.*e-mail:lfnazar@uwaterloo.ca.them.Sulphur or sulphur-containing organic compounds are highly electrically and ionically insulating 9.To enable a reversible electrochemical reaction at high current rates,the sulphur must maintain intimate contact with an electrically conductive additive.Various carbon–sulphur composites have been used for this purpose,but they have limitations owing to the scale of the contact area.Typical reported capacities are between 300and 550mA h g −1at moderate rates 10.To make a sulphur-containing cathode ionically conductive,liquid electrolytes are used that act not only as a charge transport medium but also as ionic conductors within the sulphur-containing cathode 11.This presents difficulties of electrolyte access.Another major hurdle is capacity degradation on repeated discharge–charge of the cell.This is mainly due to the high solubility of the polysulphide anions formed as reaction intermediates in both discharge and charge processes in the polar organic solvents used in electrolytes 12.During cycling,the polysulphide anions can migrate through the separator to the Li negative electrode whereupon they are reduced to solid precipitates (Li 2S 2and/or Li 2S),causing active mass loss.In addition,the solid product that extensively precipitates on the surface of the positive electrode during discharge becomes electrochemically irreversible,which also contributes to active mass loss 13.In response to these considerable challenges,novel advances in materials design such as new electrolytes 14–17and protective films for the lithium anode have been developed 18–binations of electrolyte modification,additives and anode protection have resulted in some promising results,although rates are not given 21.Much of the difficulty still remains at the cathode,where the lack of breakthroughs has led to some cell configurations in which all of the sulphides are solubilized (so-called ‘catholyte’cells)22.In the opposite approach,that is,to contain the sulphides,some interesting cathode developments have been reported recently 23–26.However,they still fall short of the mark for practical electrochemical performance.They include,for example,the fabrication of disordered mesoporous carbon/sulphur 50:50composites in conjunction with ionic liquid electrolytes;systems that achieve high initial capacity,but suffer extensive capacity0.20.40.60.81.01.21.4x in Li x S CMK¬3+S mixtureCMK¬3/S 155 °CV o l t a g e (V ) v e r s u s L i /L i +V o l t a g

increase in capacity in d is due to the encapsulation effect.fading posites with sulphur embedded in conducting polymers have shown some promising results 27.However,a large polarization was observed,resulting in a very low operating voltage that reduces the energy density of cells.The loading of active mass in the S-polymer composite is also limited (less than 55wt%)owing to the low surface area of the conducting polymer.Here,we demonstrate that cathodes based on nanostructured sulphur/mesoporous carbon materials can overcome these challenges to a large degree,and exhibit stable,high,reversible capacities (up to 1,320mA h g −1)with good rate properties and cycling efficiency.Our proof-of-concept studies are based on CMK-3,the most well-known member of the mesoporous carbon family,although they are not limited to this material.Highly ordered mesoporous carbons exhibit a uniform pore diameter,very high pore volume,interconnected porous structure and can exhibit high conductivity 28,29.They,and their oxide analogues 30,31,have attracted much attention recently as nanoscale electrode materials in Li batteries 32,33,as supercapacitors and as supports for proton-exchange-membrane fuel-cell catalysts 34.CMK-3was synthesized by a nanocasting method that uses silaceous SBA-15as a hard template.The resulting replica comprises an assembly of hollow 6.5-nm-thick carbon rods separated by empty 3–4-nm-wide channel voids 35.The channel space is spanned by carbon microfibres that prevent the collapse of the nano-architecture of the two-dimensional hexagonally ordered carbon rods.We tuned the synthesis of the CMK-3to produce a short rod-like morphology,to optimize access to the mesoporous channels 36.The CMK-3/sulphur composite was prepared following a simple melt-diffusion strategy.A 3:7weight ratio mixture of CMK-3and sulphur was heated just above the melting point of sulphur,where the viscosity is lowest 37.The melt is imbibed into the channels by capillary forces,whereupon it solidifies and shrinks to form sulphur nanofibres that are in intimate contact with the conductive carbon walls.The scanning electron microscopy (SEM)images in Fig.1reveal the changes in the mixture of CMK-3and sulphur before and after heating.The bulk sulphur evident in the SEM image of the composite on initial mixing (Fig.1a)largely disappears at 145◦C (see Supplementary Fig.S1),and completely disappears after heat treatment at 155◦C (Fig.1b).Full incorporation of sulphur into the channels of CMK-3occurs at this latter temperature.CMK-3and sulphur are both hydrophobic materials,which accounts for the ready absorption of sulphur into the channel structure.The filling of the carbon channels with sulphur is corroborated by the transmission electron microscopy (TEM)image shown in Fig.2a,along with the magnified image shown in Fig.2b.The fibres have a similar diameter to that of the channels of the mesoporous carbon (3.3nm),and a comparable diameter to the carbon nanorods that enclose them (6–7nm).The filling of the pores with sulphur,of similar density to carbon,is also evident from the decrease in contrast in relation to CMK-3itself (shown in the inset in Fig.2b).The sulphur and carbon elemental maps (Fig.2c,d)clearly demonstrate that sulphur is homogeneously distributed in the framework of the mesoporous carbon,with no significant fraction on the external surface.The marked diminution3 nm6.5 nmC Ka1_2S Ka1S meltS xtalx abc def30 nmFigure 2|TEM image and elemental maps of a

the result of the decrease in the scattering contrast (Fig.3a)paring the wide-angle XRD patterns in Fig.3b,the well-resolved peaks corresponding to bulk crystalline sulphur completely disappear after sulphur impregnation,and thermogravimetric analysis (TGA;Supplementary Fig.S2)shows the composites range up to 70wt%sulphur.A schematic diagram illustrating the impregnation of the CMK-3with sulphur is shown in Fig.2e,showing the alignment of the channels in comparison with the inset of Fig.2b.Note that most of the sulphur is contained within the interior of the pore structure,as the particles span hundreds of carbon channels in width.The average CMK-3particle size is of the order of 1µm (Fig.1b).Table 1summarizes the physical characteristics of the CMK-3and the CMK-3/S composite derived from Brunauer–Emmett–Teller (BET)and conductivity measurements.After imbibition of the sulphur in the channels,the pore size of the CMK-3/S composite decreases markedly,indicating that the channels of CMK-3are partially filled.Along with the presence of residual micropores in the carbon wall structure 39,this allows ingress of electrolyte within the structure.Empty volume within the pores is also necessary to accommodate the uptake of Liions,I n t e n s i t y2 (°)I n t e n s i t yi abθ2 (°)θFigure 3|XRD patterns of CMK-3/S before and after heating.a ,Low-angle XRD patterns of a mixture of

lower density of Li 2S (1.66g cm −3)compared with sulphur.Note that the 70wt%sulphur/composite ratio is less than the theoretical limit of 79wt%sulphur/composite based on the pore volume of CMK-3(2.1cm 3g −1)and the density of liquidized sulphur (1.82g cm −3),and is precisely tuned for the volume expansion (see the Methods section).Using even lower S/carbon ratios provides less ‘stuffed’structures and extra porosity,but at the expense of reduced active mass.Most importantly,the electrical conductivity of the composites (∼0.2S cm −1for 70wt%sulphur/composite)is the same as its mesoporous carbon counterpart.The insulating sulphur merely occupies the empty channels in the mesoporous carbon and does not block the electrical current transporting paths.Three-dimensional,multiple electronic contacts are provided by the numerous carbon interconnects that span the channels,as illustrated schematically in Fig.2e,f (ref.35).Coin cells using a metallic Li anode were assembled to evaluate the materials.All of the capacity values in this article are calculated on the basis of sulphur mass.The first discharge–charge curve for a typical nanostructured CMK-3/S cathode is shown in Fig.1d alongside its SEM image,and is compared with a simple physical (unheated)mixture of 7:3weight ratio of sulphur and CMK-3in Fig.1c.The nanostructured composite exhibits an impressive capacity of 1,005mA h g −1.In contrast,the ‘macro-mixture’exhibited a reversible capacity of 390mA h g −1(on average between 300and 420mA h g −1),similar to that

very close to that obtained for unmodified CMK-3/S obtained at elevated temperature under ‘quasi-equilibrium’conditions shown in the upper panel (CMK-3/S-155recorded at 55◦C at 168mA g −1on discharge to 1.0V followed by quasi-equilibrium discharge at 16.8mA g −1).The slight overcharge in the latter case is due to dissolution of some polysulphide,which is minor even at these conditions.This also indicates that storage of the cell at partial or full discharge does not lead to significant capacity loss.b ,Cycling stability comparison of CMK-3/S-PEG (upper points,in black)versus CMK-3/S (lower

first discharge–charge cycle is 99.94%without any overcharge,with virtually no irreversibility.This indicates that a very low fraction of polysulphide anions diffuse into the electrolyte.The polarization was decreased by more than a factor of three,owing to the greatly enhanced electrical contact achieved in the nanostructure.Further unequivocal proof of the effectiveness of the contact arises from experiments in which the degree of S incorporation was varied.Nanostructured composites (CMK-3/S-145)with the same S/C ratio,but heated at 145◦C instead of 155◦C result in less complete diffusion of sulphur into the channels because of the higher viscosity at the lower temperature.These composites showed less utilization of sulphur (capacity of 780mA h g −1)in the first discharge sweep (see Supplementary Fig.S3),and an irreversible capacity of 50mA h g −1on plete imbibition prevents sulphur agglomerates on the externalsurface of the mesoporous framework that would have poorer electrical wiring of the conductive carbon phase.These results are superior to those reported for sulphur in contact with multi-walled carbon nanotubes.Such composites exhibit lower capacities and a large electrochemical hysteresis 23.Although the sulphur is apparently confined in the carbon,the contact is limited owing to the relatively large diameter (∼50nm)of the multi-walled carbon nanotubes,and hence of the sulphur fibres within them.Thus,the efficiency of electron transfer to the sulphur mass and accessibility to the Li +electrolyte has a vitally important role in determining the electrochemical behaviour.As seen in Fig.1d,there are two plateaux in the discharge process.The first,which contributes a minor part to the overall capacity from 2.4to 2.0V,corresponds to the conversion from elemental sulphur (S 8)to Li polysulphide anions (Li 2S x ;where x is typically 4–5).The kinetics of this reaction is fast 40.The second plateau atHeat flow (W g ¬1)W e i g h t

itself (dashed lines),showing the shift to higher temperature of the PEG release on bonding to the CMK-3framework.around 2.0V is due to the conversion of polysulphides to Li 2S 2and then to Li 2S,which occurs at a much slower rate.As we achieve a nominal reversible capacity of Li 1.2S in the nanostructured composite,we wanted to explore the limitations to full conversion.To gain a measure of the reversible capacity under conditions where the kinetics should be a minimal concern,we carried out discharge of the CMK-3/S cathode at 55◦C at 168mA g −1to a cutoff of 1.0V,and allowed the voltage to relax to equilibrium.We then switched the discharge current to a rate of 16.8mA g −1to the end of discharge,and completed charge at 168mA g −1.The electrochemical profile is presented in Fig.4a (upper panel).Under these close-to-equilibrium conditions of full discharge,we achieve a reversible capacity of 1,400mA h g −1—84%of the theoretical capacity (1,675mA h g −1)—indicating that indeed,the kinetics of the last reaction step has a role in capacity limitation.The other factor could be a transport problem.There is progressively more limited accessibility of Li +ions and electrolyte to the sulphur mass towards the end of discharge because the pores become filled with insoluble Li x S (x =1–2)—even though at 70wt%sulphur loading,there is sufficient space for the volume expansion based on the conversion of S to Li 2S.However,we observed that in doubling the rate from 168to 336mA g −1(equivalent to C/5rate),the capacity is reduced by only a small amount to 930mA h g −1(see Supplementary Fig.S4).The mesoporous carbon clearly performs very well as a sulphur container.This is apparent from the small degree of overcharge even under rigorous (55◦C;C/100discharge)conditions as shown in Fig.4a.The complete lack of a sharp minimum in the discharge curve between the two plateaux,as observed by others and ascribed to supersaturation of the electrolyte with S 2−(refs 21,41),is also indicative of the strong extent of sulphide containment in our case.Experiments were carried out to evaluate the degree of self-discharge,by taking the cell to a voltage of 2.1V,holding it at the open-circuit voltage for 24h and then completing discharge.The discharge capacity after relaxation was 5%less than the cell taken to full discharge without the open-circuit voltage step.However,this suggests that the framework still allows for some egress of dissolved sulphur species.We propose that the complex inner pathway and porous,absorptive carbon greatly retard the diffusion of the bulky polysulphide anions out from the channels into the electrolyte,butcannot entirelyprevent it.This is evident by the very slow capacity fading shown in Fig.4b(upperred points).To further trapthe highly polar polysulphide species,we adjusted the hydrophilicity of the carbon external surface afterabcd300 nmFigure 6|Changes in surface morphology of

profile of CMK-3/S-PEG is shown in Fig.4a (lower panel).Not only is the initial discharge capacity increased to 1,320mA h g −1(approaching the ‘equilibrium’limit for CMK-3/S of 1,400mA h g −1),and the polarization decreased to low values,but no fading is observed in the second 10cycles and the capacity is stabilized at 1,100mA h g −1on cycling (Fig.4b,upper black points).The entrapment of sulphur active mass on cycling in the polymer-modified CMK-3/S composite is demonstrated in Fig.4c.To measure the degree of sulphur retention in the cathode,a 1.0M LiPF 6solution in a sulphur-free solvent,tetra(ethylene glycol)dimethyl ether (TEGDME),was used as the electrolyte.Glyme solvents are known for their excellent ability to dissolve polysulphides,and hence represent an ‘aggressive’pared with the cathode made of a mixture of sulphur and acetylene black that loses 96%of the total active mass into the electrolyte after 30cycles,the polymer-modified composite shows significant retention of sulphur.Only 25%of the total active mass is solubilized in the electrolyte after 30cycles.The polysulphide retention is also improved in relation to CMK-3/S.We believe that the effect of the PEG-functionalized surface is twofold.First,it serves to trap the polysulphide species by providing a highly hydrophilic surface chemical gradient that preferentially solubilizes them in relation to the electrolyte.Second,by limiting the concentration of the polysulphide anions in the electrolyte,the redox shuttle mechanism is curtailed to a large degree.Deposition of insoluble sulphur species on the surface of the Li electrode and formation of irreversible Li 2S on the cathode surface are strongly inhibited.The last point is clearly demonstrated in SEM images of the PEG-functionalized CMK-3/S cathode before and after cycling,which exhibit very little change in surface morphology (Fig.6),compared with CMK-3/S,which clearly shows precipitation of insoluble products on the surface of the mesoporous carbon particles.In summary,we demonstrate that the strategy illustrated here provides a versatile route to nanostructured polymer-modified mesoporous carbon–sulphur composites that display all of the benefits of confinement effects at a small length scale.Intimate contact of the insulating sulphur and discharge-product sulphides with the retaining conductive carbon framework at nanoscaledimensions affords excellent accessibility of the active material. The carbon framework not only acts as an electronic conduit to the active mass encapsulated within,but also serves as a mini-electrochemical reaction chamber.The entrapment ensures that a more complete redox process takes place,and results in enhanced utilization of the active sulphur material.This is vital to the success of all conversion reactions to ensure full reversibility of the back-reaction.The polymer coating on the external surface of the composite further helps retard diffusion of polysulphide out of the cathode structure,minimize the loss of the active mass in the cathode and improve the cycling stability.The composite materials reported here can supply up to nearly80%of the theoretical capacity of sulphur(1,320mA h g−1),representing more than three times the energy density of lithium transition-metal oxide cathodes,at reasonable rates with good cycling stability.In our laboratory,mesoporous carbon frameworks with various wall thicknesses,conductivities and connectivities have recently been prepared to take advantage of structural and electronic variation of the constraining support.The three-dimensional variants such as CMK-1and CMK-8are particularly promising in this respect42. We will report those results in a forthcoming paper.Owing to the flexibility of the method,the high capacity of the carbon for active material incorporation and facile functionalization of the surface,we believe that a wide variety of nanostructured‘imbibed’composites could find broad application in many areas of materials science,not only as advanced electrode materials that rely on assimilation and conversion reactions.MethodsSynthesis.For the synthesis of SBA-15with controlled morphology43,2g of Pluronic P123(EO20PPO70EO20)was dissolved in60ml of2M HCl at38◦C. Tetraethylorthosilicate(4.2g)was added to the above solution with vigorous stirring.The mixture was stirred for only6min and remained quiescent for24h at38◦C.The mixture was subsequently heated at100◦C for another24h in an autoclave.The as-synthesized SBA-15with short-rod morphology was collected by filtration,dried and calcined at550◦C in air.A nanocasting method was used to fabricate CMK-3from SBA-15as a hard template44.Sucrose(1.25g)was dissolved in5.0ml of water containing0.14g H2SO4.Surfactant-free SBA-15(1.0g)was then dispersed in the above solution and the mixture was sonicated for1h;heated at100◦C for12h and at160◦C for another12h.The impregnation process was repeated once with another5.0ml aqueous solution containing0.8g sucrose and 0.09g H2SO4.The composite was completely carbonized at900◦C for5h in an argon atmosphere.To remove the SBA-15silica template,the composite was stirred in a5%HF solution at room temperature for4h,although NaOH can also be used to dissolve the silica.The CMK-3/S nanocomposite was prepared following a melt-diffusion strategy.CMK-3(1.0g)and sulphur(2.33g)were ground together,and heatedto155◦C.The weight ratio of sulphur/carbon was adjusted to be equal to or less than7:3,to allow for expansion of the pore content on full lithiation to Li2S.For example,1.0g of CMK-3can accommodate3.486g of Li2S(1.66g cm−3(density of Li2S)×2.1cm3g−1,the pore volume of the CMK-3),which corresponds to a maximum of2.425g of sulphur.To prepare the CMK-3/S-PEG composite,CMK-3was first functionalized with carboxylic groups by oxidization treatment in concentrated HNO3solution for half an hour at80◦C,before incorporation of the sulphur.To tether the PEG chains to the surface of the CMK-3/S composite,the composite was dispersedin a PEG aqueous solution and the solution was heated at58◦C and stirred continuously overnight to ensure complete reaction of the carboxylic groups on the carbon particles with the hydroxyl groups on the PEG.The mixture was sonicated for20min to completely remove physically absorbed PEG on the composite,and the CMK-3/S-PEG composite was collected by filtration and dried. Characterization.X-ray diffraction patterns at low-angle(0.75◦to4◦2θ)and wide-angle(from10◦to80◦2θ)were collected on a D8-ADVANCE powderX-ray diffractometer operating at40kV and30mA and using Cu-Kαradiation (λ=0.15406nm).Nitrogen adsorption and desorption isotherms were obtained using a Micromeritics Gemini2735system at−196◦C.Before measurement of CMK-3,the sample was degassed at150◦C on a vacuum line following a standard protocol.It was not possible to carry this out for CMK-3/S owing to the volatility of the sulphur,and so no pretreatment was used.The BET method was usedto calculate the surface area45.The total pore volumes were calculated fromthe amount adsorbed at a relative pressure of0.99.The pore size distributions were calculated by means of the Barrett–Joyner–Halenda method applied to the desorption branch46.As the mesopores of CMK-3/S are decreased to micropores on(partial)filling with sulphur,the possibility of water entrapment,and/or pore blockage means that the values represent lower estimates.The morphology of the sulphur/CMK-3composites were examined by SEM using a LEO1530field-emission SEM instrument or a Hitachi S-5200 instrument.TEM was carried out on a Hitachi HD-2000STEM.Conductivity measurements were carried out at room temperature using the four-point method.Sample bars for the measurement were cut from the pellets and then cold pressed using a force of45kN.Elemental analyses were carried out at M-H-W Laboratories,Phoenix,USA.Electrochemistry.Positive electrodes were comprised84wt%CMK-3/S composite,8wt%Super-S carbon and8wt%poly(vinylidene fluoride)binder. The cathode materials were slurry-cast from cyclopentanone onto a carbon-coated aluminium current collector(Intelicoat).The electrolyte is composed of a1.2M LiPF6solution in ethyl methyl sulphone47.Lithium metal foil was used as the counter electrode.The equivalent current density for the168mA g−1rate is0.19 and0.37mA cm−2for the336mA g−1rate.To measure the degree of sulphur retention in the cathode,a1.0M LiPF6solution in TEGDME was used as the electrolyte.Cathodes comprising CMK-3/S-PEG were compared with simple mixtures of sulphur and acetylene black at the exact same S/C ratio.We used large Swagelok-type cells that accommodate a sufficient excess of the electrolyte to dissolve sulphur species.Swagelok cells were disassembled and immersed into TEGDME to completely extract sulphur species from the electrolyte.Sulphur analysis was carried out by Galbraith Laboratories(Tennessee,USA).Received10September2008;accepted17April2009; published online17May2009References1.Winter,M.&Brodd,R.Batteries,fuel cells and supercapacitors.Chem.Rev.104,4245–4269(2004).2.Bruce,P.G.Energy storage beyond the horizon:Rechargeable lithium batteries.Solid State Ion.179,752–760(2008).3.Rauh,R.D.,Abraham,K.M.,Pearson,G.F.,Surprenant,J.K.&Brummer,S.B.A lithium/dissolved sulfur battery with an organic electrolyte.J.Electrochem.Soc.126,523–527(1979).4.Shim,J.,Striebel,K.A.&Cairns,E.J.The lithium/sulfur rechargeable cell.J.Electrochem.Soc.149,A1321–A1325(2002).5.Kang,K.,Meng,Y.S.,Bréger,J.,Grey,C.P.&Ceder,G.Electrodes withhigh power and high capacity for rechargeable lithium batteries.Science311, 977–980(2006).6.Peled,E.&Yamin,H.Lithium/sulfur organic battery.Prog.Batteries Sol.Cells5,56–58(1984).7.Chu,M.-Y.Rechargeable positive Patent US5686201(1997).8.Peramunage,D.&Licht,S.A solid sulfur cathode for aqueous batteries.Science261,1029–1032(1993).9.Dean,J.A.(ed.)Lange’s Handbook of Chemistry3rd edn,3–5(McGraw-Hill,1985).10.Cunningham,P.T.,Johnson,S.A.&Cairns,E.J.Phase equilibria inlithium–chalcogen systems:Lithium–sulfur.J.Electrochem.Soc.119,1448–1450(1972).11.Choi,J.-W.et al.Rechargeable lithium/sulfur battery with suitable mixedliquid electrolytes.Electrochim.Acta52,2075–2082(2007).12.Rauh,R.D.,Shuker,F.S.,Marston,J.M.&Brummer,S.B.Formationof lithium polysulfides in aprotic media.J.Inorg.Nucl.Chem.39,1761–1766(1977).13.Cheon,S.-E.et al.Rechargeable lithium sulfur battery II.Rate capability andcycle characteristics.J.Electrochem.Soc.150,A800–A805(2003).14.Shin,J.H.&Cairns,E.J.Characterization of N-methyl-N-butylpyrrolidiniumbis(trifluoromethanesulfonyl)imide-LiTFSI-tetra(ethylene glycol)dimethyl ether mixtures as a Li metal cell electrolyte.J.Electrochem.Soc.155,A368–A373(2008).15.Yuan,L.X.et al.Improved dischargeability and reversibility of sulfur cathodein a novel ionic liquid mun.8,610–614(2006).16.Ryu,H.-S.et al.Discharge behavior of lithium/sulfur cell with TEGDME basedelectrolyte at low temperature.J.Power Sources163,201–206(2006).17.Wang,J.et al.Sulfur-mesoporous carbon composites in conjunction with anovel ionic liquid electrolyte for lithium rechargeable batteries.Carbon46, 229–235(2008).18.Chung,K.-I.,Kim,W.-S.&Choi,Y.-K.Lithium phosphorous oxynitride as apassive layer for anodes in lithium secondary batteries.J.Electroanal.Chem.566,263–267(2004).19.Visco,S.J.,Nimon,Y.S.&Katz,B.D.Ionically conductive composites forprotection of active metal Patent7,282,296,October16(2007). 20.Skotheim,T.A.,Sheehan,C.J.,Mikhaylik,Y.V.&Affinito,J.Lithium anodesfor electrochemical patent7247,408,July24(2007).21.Akridge,J.R.,Mikhaylik,Y.V.&White,N.Li/S fundamental chemistry andapplication to high-performance rechargeable batteries.Solid State Ion.175, 243–245(2004).。

The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT40°CEmergency temperature (Tₑ)35°CControl temperature (Tc)30°CMethod The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria – United Nations,New York and Geneva).StorageDue to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts max.20°C (please see note below)Note When stored under the recommended storage conditions, Perkadox® 16 willremain within the Nouryon specifications for a period of at least 3 months afterdelivery. The Ts max of 20°C is not to be interpretated as ambient or roomtemperature as this differs per region and season. Perkadox® 16 has a high qualitycomposition and to hold that it should be stored at below 20°C. At temperaturesabove 20°C the decomposition of Perkadox® 16 progresses fast which leads tosignificant loss of quality. If you have questions about this, please contact yourlocal Nouryon account manager for advice.Packaging and transportIn North America Perkadox® 16 is packed in non-returnable cartons containing 25 polyethylene bags of 1 lb net weightor 5 polyethylene bags of 5 lb net weight. In other regions the standard packaging is a cardboard box for 20 kg peroxide. Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your Nouryon representative. Perkadox® 16 is classified as Organic peroxide type C; solid, temperature controlled; Division 5. 2; UN 3114.Safety and handlingKeep containers tightly closed.

IntroductionIridium telephones were originally designed to operate with a passive antenna, either an element attached directly to the handset, or a remote aerial connected with a short length of coaxial cable. Unfortunately, a signal loss of more than 3dB in a remote antenna’s connecting cable degrades performance due to attenuation of both the received and transmitted signals. A 3dB loss corresponds to approximately 10m of RG213U or 3m of RG58U coaxial cable, lengths that clearly restrict the mounting options for the antenna using standard down-leads.AD511-2 active Iridium antenna (figure 1 & figure 2) is designed for use with up to 160 meters of coaxial cable terminated with type ‘N’ connectors, and with coax lengths starting from 27meters – subject to AST advice.Designed for harsh environments, the AD511-2 consists of two RHCP dipole antenna housed within a 4mm thick GRP radome mounted on a common base. One antenna is for signal transmission and one for reception.AD511-2 has a linear power amplifier within the base and connected to the transmitting antenna compensates for signal loss incurred mainly by the connecting cable. Similarly, a low noise amplifier is attached to the receiving antenna via a low loss interdigital filter to boost the signal sent to the telephone. The interdigital filter has a bandwidth of 25 MHz centered on the Iridium band designed to attenuate any out of band interference that may arise, for example from nearby Inmarsat uplinks. Using manufacturing techniques proven for a range of extremely rugged GPS/DGP active antenna, the base is milled from aluminium and hard anodised, giving an attractive grey finish, which is mechanically resilient and resistant to corrosion. The antenna’s mass is 0.8kg.3.Mounting and OperationAD511-2 should be mounted with an unobstructed view of the sky. An aluminium bracket with V-bolts is provided to attach the antenna to horizontal or vertical masts or spars up to 50mm in diameter, figure 2. The bracket is shipped inverted at the centre of the AD511-2 antenna and should be detached, inverted, then reattached to antenna case using the mounting holes in the base.The coaxial down-lead is attached to the N-type connector on the underside of the antenna, figure 2. Wrapping the connectors with self-amalgamating tape is recommended for permanent installations and the cable should be taped or strapped to the spar as appropriate.AD511-2 antenna supplied with coaxial down-leads must be used with the accompanying AD511-3 DC Power Break-In Box (figure 3), which accepts +18V to +36V DC at 500mA. The down-lead must not be shortened by the user.AD511-3 Power Break-In should be positioned close to the telephone base- station or handset. The coaxial down-lead is then attached to the N type connector on the AD511-3 (figure 3 & figure 4).Earthing: - the AD-511-3 power breaking box is provided with an earth terminal. The box should be earthed via this connection with a short earthing lead connection to the system earth. Connection between the telephone and the AD511-3 is made with a coaxial cable terminated with TNC connectors. An adapter is provided with the Iridium handset, which enables a TNC terminated cable to be attached to the telephone. AD511-3 case has drilled flanges to enable permanent fixing.A 1m flying lead for the AD511-3 Power Break-In Box is provided for connection to the DC supply (+18 to 36 v DC at 500mA), which can be trimmed (or extended) if necessary. The red wire is connected to supply positive, whilst the blue wire is for either an isolated or grounded negative supply. AD511-3 is protected against output short-circuiting by a fuse, which is resettable by disconnecting the unit from the +18 to +36 v DC supply.With all connections made, the telephone can then be turned on and used as normal - it is transmitting into a load impedance equivalent to a matched passive antenna. The gains of the antenna transmitter and receiver are factory set to compensate for the total attenuation between the telephone and the antenna, mainly determined by the coaxial down-lead. Consequently, the signal output level and frequency from the antenna is equivalent to that radiating from a passive antenna mounted directly on the handset, subject to the antenna transmitter being a linear device. Transmitter linearity is verified with test protocols using an HP 8591 EMC analyser that also ensure there are no spurious out of band emissions.4. FiguresFigure 1.

General InformationSemiconductor manufacturers use the vision system of automatic pick and place equipment during the assembly process to detect damaged and/or rejected die. This is done by shining a combination of different lights on the wafer surface to create a “white” background. Ink dots and defects such as chipped corners are easily recognizable against this background.Xandex 8103, 8104, 7824, 7824T and Markem 6993 inks are opaque and easily recognizable under all lighting conditions. Xandex Glycol Free 8103 ink is thick in viscosity and delivers opaque dots ranging from 6 to 40 mils. Xandex 8104 is not as viscous as 8103 and provides thinner dots with excellent geometry and adhesion in a larger dot range up to 86 mils. Markem 6990 and 6997 are less opaque and may not offer sufficient contrast under all lighting conditions. Xandex 8103 ink is certified to contain less than 10 ppm of Sodium (Na) and Chloride (Cl). Xandex 8104 ink is certified to contain less than 20 ppm of Sodium (Na) and Chloride (Cl). Both 8103 and 8104 premium inks are free of glycol ethers, which are identified reproductive hazards and carcinogens. Xandex 7824 and 7824T inks are certified by Xandex to contain less than 10 ppm of Na and Cl. Markem 6990 is certified by Markem to contain less than 25 ppm of Na and Cl. Analysis reports are available upon request from Xandex Customer Service. Although Markem 6993 and 6997 are not contaminant controlled, periodic test data indicates that these inks typically contain less than 100 ppm of Sodium (Na) and 300 ppm of Chloride (Cl). These levels are not certified or guaranteed by Markem or by Xandex1.Xandex Glycol Free 8103 and 8104 inks have a 4 month shelf life, rapidly air dry at ambient conditions and will give consistent flow for 3 days after cartridge opening. Markem 6990, 6993 and 6997 inks have a 4 month shelf life, require heat curing to be permanent, and will give consistent flow for 5 days after cartridge opening. Xandex 7824 and Xandex 7824T inks have a 4 month shelf life and will give consistent flow for 3 days after cartridge opening. Xandex 7824 and 7824T can be air or “heat set” cured.Xandex Glycol Free 8103 and 8104 inks are thermally stable at temperatures up to 150° C and can be used in hot chuck or oven drying applications without cracking or loss of adhesion. Use of either Markem 6990, 6993 and 6997 or Xandex 7824 and 7824T inks in hot chuck applications is not recommended as the elevated ambient temperature in the probing area can reduce cartridge life and cause inconsistent ink flow. However, use of a hot chuck to heat set dots during offline inking has reportedly been successful when employed by some customers. All of the inks offered by Xandex are non-magnetic.Material Safety Data Sheets (MSDS) are available for all inks offered by Xandex.

Ink Ink CuringInk CuringThe procedure for curing will depend on the type of ink used. Markem 6990, 6993, and 6997 should be cured/baked within 2 hours of inking due to the evaporation of solvents in the ink over time. If a wafer (or boat of wafers) is left on the prober for an extended period of time, the dots may crack and/or flake after the baking process.Markem 6990, 6993, and 6997 inks, which are air-dried, will not smear when touched. They are not permanent, however, and will not withstand most post-probe handling or processes. Conversely, Xandex 7824 and 7824T inks air cure within 2.5 hours (≤20 mil, up to 8 hours for >20 mil dots). Xandex 7824 and 7824T may also be “heat set” at 120°C for 10 minutes. Xandex 8103 and 8104 Glycol Free inks hard cure under ambient conditions in the least time of any of the inks offered by Xandex. Ink dots of ≤25 mil air dry to a hard cure in 45 minutes.

An ultrasonic bath is recommended to ensure complete removal of ink residue. Ink dots, which have been air dried or hard cured, require the application of an ink remover.DieMark Remover 8000Xandex has developed DieMark Remover 8000 specifically for the semi-conductor industry. DieMark Remover 8000 thoroughly removes all inks supplied by Xandex, including oven baked ink dots. DieMark Remover 8000 has very low levels of organic and inorganic contaminants and is an efficient and thorough ink remover when used in simple bench top cleaning methods. Due to its high flash point, DieMark Remover 8000 is also safe and effective when used in ultrasonic, temperature/pressure cycling under vacuum and deep bath heating and agitation ink removal processes.DieMark Remover 8000 is carcinogen free (NTP, OSHA) and all ingredients used are TSCA listed. For an MSDS or more information on using DieMark Remover 8000 in your specific ink removal process, contact Xandex Customer Service.Ink Removal ProcedureThe following is the recommended bench top procedure for removing ink from wafers using DieMark Remover 8000. *1. Apply sparingly with an eyedropper to a localized area of the wafer.2. Allow 2-3 minutes for the DieMark Remover 8000 to begin solvating. Time requiredwill vary depending on the degree that the ink was cured.3. For highly cured ink dots, use longer soak times, then wipe gently with a clean lint-free cloth to facilitate removal. If necessary, repeat steps 1 and 2.4. For large areas or removal of ink from entire wafer, soak a clean lint-free cloth withDieMark Remover 8000, then lay the wet cloth over the entire surface and allow timeto soak/solvate ink, then remove wet cloth. Repeat as necessary.5. After dots are removed, clean wafer via standard procedures, such as vapor degreas-ing, and/or rinse with a clean solvent (Isopropyl Alcohol) followed by a bake cycle at65° C to dry.REV F 09/03* The following ink removers may be substituted for DieMark Remover 8000, however, Xandex does not guarantee that satisfactory results will be obtained.
