圆筒形锂电池生产工艺流程英语Cylindrical Lithium-Ion Battery Production Process.Cylindrical lithium-ion batteries are a common type of battery used in various electronic devices, such as laptops, smartphones, and power tools. The production process of cylindrical lithium-ion batteries involves several key steps:1. Raw Material Preparation.The first step in the production process is the preparation of the raw materials. The main raw materials used in the production of cylindrical lithium-ion batteries are lithium, cobalt, nickel, manganese, and aluminum. These materials are obtained from various sources and are processed to meet the required specifications.2. Cathode and Anode Production.The cathode and anode are the two electrodes of a lithium-ion battery. The cathode is typically made of a lithium-metal oxide compound, such as lithium cobalt oxide (LiCoO2) or lithium nickel manganese cobalt oxide (NMC). The anode is typically made of a carbon-based material, such as graphite or silicon.The cathode and anode materials are synthesized through a series of chemical processes. The cathode material is typically synthesized by mixing lithium salts with metal salts and then heating the mixture at high temperatures. The anode material is typically synthesized by mixing carbon precursors with a binder and then heating the mixture at high temperatures.3. Electrode Coating.Once the cathode and anode materials have been synthesized, they are coated onto metal current collectors. The current collectors are typically made of aluminum or copper. The cathode material is coated onto the positive current collector, and the anode material is coated ontothe negative current collector.The electrode coating process is typically carried out using a slurry method. The cathode or anode material is mixed with a solvent and a binder to form a slurry. The slurry is then coated onto the current collector using a doctor blade or a slot die coater.4. Electrode Drying and Calendering.After the electrodes have been coated, they are dried to remove the solvent. The electrodes are then calendered to improve their density and electrical conductivity. Calendering is a process in which the electrodes are passed through a series of rollers under pressure.5. Cell Assembly.The next step in the production process is the cell assembly. The cell assembly process involves stacking the electrodes together with a separator between them. The separator is a porous material that prevents the electrodesfrom making contact with each other and causing a short circuit.The electrodes and separator are typically stacked together in a winding machine. The winding machine rolls the electrodes and separator into a cylindrical shape.6. Cell Formation.Once the cells have been assembled, they are subjected to a formation process. The formation process involves charging and discharging the cells several times under controlled conditions. The formation process helps to stabilize the electrochemical reactions within the cells and improve their performance.7. Cell Testing.After the cells have been formed, they are tested to ensure that they meet the required specifications. The cells are tested for capacity, voltage, and internal resistance. The cells that do not meet the specificationsare rejected.8. Cell Packaging.The final step in the production process is the cell packaging. The cells are typically packaged in a metal can or a plastic pouch. The packaging protects the cells from the environment and prevents them from being damaged.The cylindrical lithium-ion battery production process is a complex and multi-step process. The quality of the batteries depends on the quality of the raw materials, the precision of the manufacturing processes, and the quality control procedures.。

Make into positive and negative pasty materials after stirring at high speed till uniformity.Coating（涂布）Now, we are in coating line. We use back reverse coating. This is the slurry-mixing tank. The anode（Cathode）slurry is introduced to the coating header by pneumaticity from the mixing tank.

Before compress we clean the electrode with vacuum and brush to eliminate any particles. Then the compressed electrode is wound to a big roll. We use micrometer to measure the compressed electrode thickness every 10 minutes. After compressing we cut the web into large pieces. We tape the cathode edge to prevent any possible internal short. The large electrode with edge taped is slit into smaller pieces. This is ultrasonic process that aluminum tabs are welded onto cathodes using ultrasonic weld machine.

After oven drying, the cells are transferred to the process of electrolyte filling through this channel. The electrolyte filling performs in dry room. The electrolyte is injected in two times so that it can be filled easily and sufficiently. When filling, vacuum first, then inject electrolyte. After that, we repeat vacuum and vent to room pressure several times. Finally the cell is put off at room pressure, then weigh the cell in order to check the amount of electrolyte. After weighing, we seal with tape onto the filling port to prevent the cells absorbing water during storing.We store the filled cells for 24 hours at room temperature so that the electrolyte can be saturated sufficiently by the anodes and cathodes.Vocabulary:oven drying 烘烤vacuum 真空electrolyte filling 注液electrolyte 电解液room pressure 大气压filling port 注液孔storing 陈化saturated 浸润anode 正极cathode 负极Pre-charge and ball sealAt first, we place a piece of absorb cotton above the filling port to absorb the excess electrolyte.

锂电工艺流程英语Lithium battery manufacturing processLithium batteries are widely used in electronic devices, electric vehicles, and renewable energy storage systems due to their high energy density and long cycle life. The manufacturing process of lithium batteries involves a series of complex steps, each of which is essential for producing high-quality batteries. In this article, we will discuss the general process of producing lithium batteries and the key technologies involved.1. Electrode preparationThe first step in the production of lithium batteries is the preparation of electrodes. This involves the coating of a conductive substrate with an active material, which is usually a lithium compound such as lithium cobalt oxide (LiCoO2) for the positive electrode and graphite for thenegative electrode. The active material is mixed with a binder and solvent to form a slurry, which is then coated onto the substrate using a coating machine. The coated electrodes are then dried and calendared to improve their density and adhesion.2. Cell assemblyOnce the electrodes are prepared, they are assembled into a cell along with a separator and electrolyte. The separator is a thin membrane that prevents the electrodes from coming into direct contact with each other while allowing the transport of lithium ions. The electrolyte is a solution of lithium salts in a solvent, which serves as the medium for the transport of lithium ions between the electrodes. The assembled cell is then sealed in a metal casing to form a hermetically sealed unit.3. FormationAfter assembly, the cells undergo a formation process, which involves the initial charging and discharging of the cells to activate the electrodes and stabilize the electrolyte. This process is essential for achieving the desired performance and cycle life of the batteries. The formation process is typically carried out in a controlled environment with precise temperature and humidity conditions.4. Aging and testingOnce the formation process is complete, the cells undergo aging to allow for the gradual stabilization of their performance. During this period, the cells are subjected to various tests to assess their capacity, energy efficiency, and cycle life. Any cells that do not meet the specified performance criteria are rejected, while those that pass the tests are selected for further processing.5. Module and pack assemblyThe selected cells are then assembled into modules, which are groups of cells connected in series and parallel to achieve the desired voltage and capacity. The modules are then assembled into packs, which are the final products that are used in various applications such as electric vehicles and energy storage systems. The pack assembly involves the integration of battery management systems, thermal management systems, and safety features to ensure the reliable and safe operation of the batteries.6. Quality control and inspectionThroughout the manufacturing process, strict quality control measures are implemented to ensure the consistent performance and safety of the batteries. This involves the inspection of raw materials, in-process monitoring, and final product testing to identify and rectify any defects or abnormalities. The quality control measures are crucial formeeting the stringent reliability and safety requirements of lithium batteries.Key technologies in lithium battery manufacturingThe production of lithium batteries involves several key technologies that are essential for achieving high-performance and reliable batteries. These technologies include:1. Electrode coatingThe electrode coating process is a critical step in the manufacturing of lithium batteries, as it directly affects the performance and cycle life of the batteries. Advanced coating technologies such as slot die and doctor blade coating are used to achieve precise and uniform coating of the electrodes, leading to improved energy density and cycle life.2. Solvent recoveryThe solvent used in the electrode coating process needs to be recovered and recycled to minimize waste and reduce environmental impact. Solvent recovery technologies such as distillation and membrane separation are employed to recover the solvent from the slurry and reuse it in the manufacturing process.3. Electrode drying and calendaringThe drying and calendaring of the coated electrodes are essential for improving their density and adhesion, which in turn affects the performance and cycle life of the batteries. Advanced drying and calendaring technologies such as infrared heating and roll pressing are used to achieve uniform and controlled drying and calendaring of the electrodes.4. Cell assembly and sealingThe cell assembly and sealing process is crucial for preventing the leakage of electrolyte and ensuring the long-term stability of the batteries. Advanced sealingtechnologies such as laser welding and ultrasonic welding are employed to achieve hermetic sealing of the cells, leading to improved safety and reliability.5. Battery management systemsThe integration of battery management systems (BMS) inthe pack assembly process is essential for monitoring and controlling the operation of the batteries. Advanced BMS technologies with features such as cell balancing, state-of-charge estimation, and thermal management are used to ensure the safe and efficient operation of lithium batteries.6. Safety testing and certificationSafety testing and certification are essential for ensuring the reliable and safe operation of lithium batteries. Advanced testing technologies such as abuse testing, thermal runaway testing, and crush testing are employed to assess the safety performance of the batteries and obtain certification from regulatory authorities.ConclusionThe manufacturing process of lithium batteries involves a series of complex steps, each of which is essential for producing high-quality batteries. Advanced technologies such as electrode coating, solvent recovery, cell assembly, and battery management systems are employed to achieve high-performance and reliable batteries. Strict quality control measures and safety testing are essential for meeting the stringent reliability and safety requirements of lithium batteries. As the demand for lithium batteries continues to grow, the development of advanced manufacturing technologies will play a crucial role in meeting the increasing performance and safety requirements of lithium batteries.。
