摘要：

The formation of a solid electrolyte interface (SEI) on a Li-ion battery electrode during usage cycling is a critical reason for battery capacity loss. In this paper, laser ablation technology is applied to remove SEI from a graphite electrode surface. Characterization methods including scanning electron microscopy, Raman microscopy, and Fourier transform infrared spectroscopy are used to study the structure and morphology changes of the SEI on the electrode surface. The results show that laser ablation can successfully remove the SEI, indicating a feasible method to clean the electrode surface. (C) 2017 Laser Institute of America.
