POLYRADICAL COMPOUND, ELECTRODE ACTIVE MATERIAL, AND BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a polyradical compound which can serve as an electrode active material showing little reduction in repeated charge and discharge capacity. SOLUTION: As the electrode active material, there is used an electrode active material which has a repeating unit structure represented by general formula (1) and contains a polyradical compound crosslinked by a specific divalent structure. In general formula (1), R1-R3independently represent a hydrogen atom or a methyl group; R4-R5independently represent a hydrogen atom or a 1-3C alkyl group; and R6-R9independently represent a 1-3C alkyl group.
