基于棒压试验的锂离子电池内部短路安全性评估
|
摘要
从测试的角度出发,综合比较了国内外常见试验方法,提出评估锂离子电池内部短路安全性的棒压试验。试验以电池电压下降100 m V为截止条件,通过棒-平板挤压制造有效的内部短路来评估电池的安全性。按此方法对圆柱形、棱柱形和软包装等三种电池进行测试,并与部分UN38. 3 T. 6撞击/挤压数据比较。棒压试验造成短路的效果良好。
Based on the testing and the comprehensive comparison of domestic and foreign test methods,it proposed a new safety assessment method for internal short circuit of the Li-ion battery-rod crush test. The cell was crushed to effective internal short circuit by a rod and a flat surface until the voltage dropped at least 100 m V. According to the method,cylindrical,prismatic and pouch cells were tested and compared with some test data of UN38. 3 T. 6 impact/crush test. The rod crush test showed a good effective short circuit.
