PROBLEM TO BE SOLVED: To provide an electrical charge storage material which allows for manufacturing of a cell exhibiting low solubility to a solvent, and exhibiting excellent cycle characteristics with little capacity drop even if charge and discharge are repeated with high capacity, and to provide an electrode active material composed of the electrical charge storage material, an electrode containing the electrode active material, and a cell including the electrode.SOLUTION: The electrical charge storage material is composed of a thiophene ring-fused dicyano benzoquinone diimine compound represented by formula (1).(R-Rrepresent, independently, a hydrogen atom, a halogen atom, a hydroxyl group, a mercapto group, an amino group, a substituted or unsubstituted monovalent hydrocarbon group of 1-12C, a substituted or unsubstituted heteroaryl group of 3-12C, a substituted or unsubstituted alkoxy group of 1-12C, a substituted or unsubstituted alkylthio group of 1-12C, a substituted or unsubstituted mono alkylamino group of 1-12C, or a dialkylamino group where each alkyl group is a substituted or unsubstituted alkyl group of 1-12C, independently). |
