Samples after thermal degradation can be evaluated using LC/MS/MS, TOF-SIMS, TEM+EDX, etc.

The development of lithium-ion secondary batteries faces challenges such as improving performance, extending lifespan, and enhancing reliability. To address these challenges, it is important to understand the degradation mechanisms of the batteries. In this study, we conducted a heating degradation test to evaluate the degradation mechanisms caused by temperature. After the heating degradation test, we assessed samples that showed significant capacity reduction using LC/MS/MS for the electrolyte, TOF-SIMS for the anode surface, and FIB-TEM+EDX for the cross-section of the anode.
