Original Abstract Submitted

A composite particle includes a positive electrode active material particle and a coating film. The coating film covers at least part of a surface of the positive electrode active material particle. The coating film includes a phosphorus compound. The composite particle satisfies a relationship of “C/C≤2.5”. “C” represents a concentration of Li element measured by XPS. “C” represents a concentration of P element measured by XPS.
