PROCESS FOR PRODUCTION OF POLYRADICAL COMPOUND AND BATTERY CELL

摘要

Disclosed is a polyradical compound which can be used as an electrode active material for at least one of a positive electrode and a negative electrode. The polyradical compound has a repeating unit represented by the general formula (1) and is crosslinked using a bifunctional crosslinking agent having two polymerizing groups in the molecule represented by the general formula (2) [in the formulae, R¹ to R³ independently represent a hydrogen atom or a methyl group; R⁴ to R⁷ independently represent an alkyl group having 1 to 3 carbon atoms; X represents a single bond, a linear, branched or cyclic alkylenedioxy group having 1 to 12 carbon atoms, an alkylene group, a phenylenedioxy group, a phenylene group or a structure represented by the general formula (3); R⁸ to R¹³ independently represent a hydrogen atom or a methyl group; and k represents an integer ranging from 2 to 5.
