Abstract:

The performance of lithium-ion batteries is significantly influenced by the characteristics and changes occurring at their surfaces and interfaces. Using appropriate surface analysis technologies to examine the composition, structure, and distribution of these interfaces is essential. Such analyses provide critical insights for optimizing interface performance, studying ion transport behaviors, and understanding battery failure mechanisms. Auger electron spectroscopy (AES) is a surface analysis technique that utilizes an electron beam probe, offering high spatial resolution. AES is capable of performing qualitative and semi-quantitative analyses of most elements, except H and He, and their oxidation states, along with providing two-dimensional imaging. This work introduces the technical principles, main functions, and analysis methods of Auger electron spectroscopy, while also reviews its application cases in lithium batteries. It summarizes the experience gained from employing AES in this field and explores potential advancements for its application in lithium battery technology.

Key words: lithium-ion batteries, Auger electron spectroscopy, surface interface analysis
