The MST website has published analysis case studies. ◆Title Heating Degradation Test of Lithium-Ion Secondary Batteries ~Samples after heating degradation can be evaluated using LC/MS/MS, TOF-SIMS, TEM+EDX, etc.~ ◆Measurement and Processing Methods TOF-SIMS, TEM, LC/MS/MS, FIB, μ-sampling, lift-out, disassembly, atmosphere control ◆Product Field Secondary Batteries ◆Analysis Objectives Composition evaluation, identification, chemical bonding state evaluation, film thickness evaluation, degradation investigation, reliability evaluation ◆Overview The development of lithium-ion secondary batteries faces challenges such as performance enhancement, longevity, and reliability improvement. To address these challenges, understanding the degradation mechanisms of the batteries is crucial. In this instance, a heating degradation test was conducted to evaluate the degradation mechanisms due to temperature. After the heating degradation test, samples that showed significant capacity reduction were evaluated using LC/MS/MS for the electrolyte, TOF-SIMS for the anode surface, and FIB-TEM+EDX for the anode cross-section. ★★For detailed data, please refer to the link★★
