ELECTRODE ACTIVE MATERIAL FOR ELECTRICITY STORAGE DEVICE, AND ELECTRICITY STORAGE DEVICE USING SAME

摘要

Disclosed is an electrode active material for an electricity storage device, which has a structure represented by formula (1). In formula (1), R1-R6 each independently represents a hydrogen atom (excluding the case where all of the R1-R6 are hydrogen atoms), a halogen atom, an optionally substituted phenyl group, an optionally substituted heterocyclic group, or an optionally substituted hydrocarbon group having 1-4 carbon atoms.
