Remarks/备注：
1. Standard charge/充电标准：在20±5℃条件下，先以0.8C电流充电至截止电压，再以设计上限充电电
压(单体4.20V)恒压充电，截至电流为0.01CA
2. Verification and Identification/鉴定检验：鉴定检验一般在产品设计定型和生产定型时进行，但在产品的主要设计、工艺、元器件及材料有重大改变，且改变之参数影响产品的重要性能，使原有的鉴定结论不再有效时也应进行鉴定检验。
3. Sampling plan/抽样方案：鉴定检验的样品由批量生产的电池中随机抽取。
4. Criterion rule /判定规则：当所有检验项目均满足标准时则判为鉴定检验合格。

（一）、Conclusion/测试结果
External Short Circuit 外部短路
1. The cells are full charge under strict observation of the standard charging, and let stand for 1 hour. 将电池恒流恒压满充至4.2V，然后静置1h。
2. Put the samples in an oven with 60±2℃.
将感温探头贴到电池表面，装到短路装置上，然后放置到60±2℃的高温箱中。
3. Short each cell with copper wire having maximum resistance load of 50mΩ, monitor and keep 1 hour.
待电池表面温度达到60℃后，用50毫欧的铜导线将电池进行短路，保持短路状态1h。
4. Measure temperature of the exterior cell and observe the samples.
记录实验过程中的最高温度

二、Forced discharge 强制放电：
1. The cells are full charge under strict observation of the standard charging, and let stand for 1 hour.
将电池恒流恒压满充至4.2V，静置1h。
2. Completely discharge one cell of the samples with 1C current,
将其中一个电池用1C的电流完全放电。
3.The completely discharged cell is to be force-discharged by connecting it in series with the fully charged cells; the sample is to discharge until the battery case temperature has returned to ambient temperature.
将满充电池和上述完全放电的带电池串联进行强制放电，直至完全放电且电池温度接近室温。
Test requirements 实验要求：N ot explode or catch fire/不爆炸、不起火
