COMPOSITE, ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERY HAVING THE SAME AND SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a radical compound capable of satisfying both of electroconductivity and organic solvent dissolution resistance, an electrode active material containing the same and a secondary battery by using the same.

SOLUTION: The composite includes particles at least of which surfaces comprise an electroconductive carbon material and a stable radical compound having a partial structure expressed by formula (1), and the stable radical compound supported on the particles.
