Abstract
A ion-conductive fused-ring quinone polymer includes recurring units of formula (1) and/or (2) below wherein each X is independently a single bond or a divalent group, and Aand Aare each independently an aromatic hydrocarbon ring or an oxygen atom or sulfur atom-containing aromatic heterocycle that forms together with two carbon atoms on a benzoquinone skeleton. This polymer is a material having charge-storing properties which, when used as an electrode active material, is capable of providing a high-performance battery possessing high capacity, high rate characteristics and high cycle characteristics.
