Proposing an evaluation that combines structure, composition, and electricity to solve development issues.

This article introduces a case study evaluating the surface morphology, cross-sectional structure, components, composition, crystal structure, and resistance value distribution of Li(NiCoMn)O2 (NCM), which is used as a positive electrode in lithium-ion secondary batteries. Based on a comprehensive evaluation of structure, composition, and electrical properties, MST proposes assessments suitable for solving development challenges aimed at improving characteristics and enhancing reliability.
