Abstract

Abstract: 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.

Key words: lithium-ion batteries, safety, testing method, X-ray 3D CT
