Abstract: A test method for a secondary battery, which early detects the occurrence of the future micro short-circuiting in the screening and promotes to render the contaminant harmless while suppressing the short-circuiting between the positive and negative electrodes in the aging, is provided. This test method includes Step S12 of charging the secondary battery, Steps S13 and S14 of aging the secondary battery in a first pressed state, Step S17 of measuring a battery voltage (V1) after the aging, Step S18 of screening the secondary battery in a second pressed state with a higher pressure than in the first pressed state, and Step S19 of measuring a battery voltage (V2) after the screening. Whether the battery has the internal short-circuiting or not is determined (Step S20) based on the difference between the voltage (V1) measured in Step S17 and the voltage (V2) measured in Step S19.

Abstract translation: 提供二次电池的测试方法，该方法早期检测出筛选中将来的微短路的发生，并促进污染物无害化，同时抑制老化中的正极和负极之间的短路。 该测试方法包括对二次电池进行充电的步骤S12，在第一按压状态下使二次电池老化的步骤S13和S14，老化后的电池电压（V1）的测量步骤S17，将二次电池放电的步骤S18 压力高于第一按压状态的第二按压状态，以及筛选后测量电池电压（V2）的步骤S19。 基于在步骤S17中测量的电压（V1）与步骤S19中测量的电压（V2）之间的差异来确定电池是否具有内部短路（步骤S20）。
