[Analysis Case] Composition Analysis of the Surface Film on the Positive Electrode of Secondary Batteries

Evaluation of the distribution of organic components and active substances on the surface, qualitative analysis.

The segregation of components and the formation of films on the surface of the positive electrode of lithium-ion secondary batteries are factors that influence the electric capacity. We will introduce a case study on Li(NiCoMn)O2 (NCM), which is used as a positive electrode, where micro-region mapping was conducted using AES, and qualitative analysis of organic components (binder) and active material surface films was performed using XPS and TOF-SIMS. These methods allow for analysis with a series of treatments conducted under an Ar atmosphere, which helps to suppress the alteration of the sample.
