Abstract

Acoustic emission (AE) technique is nondestructive and sensitive method by detecting ultrasonic elastic waves to evaluate degradation of Li ion batteries. The AE technique was applied to a half cell (Li/ LiPF₆ (EC: DMC)/ Sn or SnO) during charge and discharge cycles. Solid electrolyte interphase (SEI) is formed by electrolyte decomposition with gas generation due to catalytic effect of Sn. The low frequency (20 ∼ 100 kHz) AE signals were detected and attributed to the gas generation due to electrolyte decomposition, which was confirmed by in-situ microscope observation. In our previous research, high frequency (100 ∼ 300 kHz) AE signals were detected due to crack formation during deintercalation process by using SnO thin film electrode. The AE signals of different origins were distinguished by specific frequencies of the AE signals. The AE technique is useful as a diagnostic tool for Li ion batteries.
