[Analysis Case] Degradation Assessment After Charge and Discharge Cycle Testing of LIB

From the production of battery cells to charge and discharge cycle testing, disassembly, and investigation of degradation components.

When investigating the degradation mechanisms of secondary batteries, it is important to analyze the deposits on the electrode surface. At MST, we conduct TOF-SIMS measurements under controlled atmospheric conditions, allowing us to evaluate the chemical state of the electrode's outermost surface without alteration due to exposure to the atmosphere. Additionally, by consistently performing measurements from charge-discharge cycle tests to the electrode surface, we can examine the correlation between the state of charge-discharge and the condition of the deposits on the electrode surface.
