CHARGE STORAGE MATERIAL, ELECTRODE ACTIVE MATERIAL AND SECONDARY BATTERY

摘要

Materials having charge-storing properties and made variously of dipyridine-fused benzoquinones of formula (1) below or derivatives thereof, dipyridine-fused benzoquinones of formula (4) below or derivatives thereof, or dipyridine-fused benzoquinone skeleton-containing polymers are provided.;;In the formulas, Ar1 and Ar2 are each independently a pyridine ring that forms together with two carbon atoms on a benzoquinone skeleton, or a derivative thereof. When used as electrode active materials, these charge storage materials are capable of providing high-performance batteries possessing a high capacity, high rate characteristics and high cycle characteristics.
