摘　　要：对锂离子电池的机械滥用、热滥用和电滥用安全性测试与评价方法的原理进行了分析,对具有代表性的锂离子电池安全测试标准GB/T 31467.3/31485和SAE J2464/UN 38.3的相关试验方法进行了对比分析。应用X射线三维CT技术,测试了安全性试验前后锂离子电池内部结构的变化,对X射线三维CT应用于锂离子电池安全性测试分析的前景进行了展望。为锂离子电池安全失效模式分析指明了方向。The mechanisms of safety testing and evaluation methods （mechanical abuse, thermal abuse and electrical abuse testing） for lithium-ion batteries were analyzed. Test methods of GB/T 31467.3/ 31485 and SAE J2464/UN 38.3, the representative safety test standards for lithium- ion batteries, were compared. X-ray 3D CT （Computed Tomography） technology was used to analyze the internal structure of lithium-ion battery before and after safety test. The prospect of X-ray 3D CT for safety test of lithium-ion battery was prospected. The direction of the safety failure mode for lithium-ion batteries analysis was indicated.
