A fused-ring quinone-substituted polynorbornene has recurring units of formula (1) and/or (2) below.
In formulas (1) and (2), A1 is independently a substituent of formula (3) or (4) below, n is an integer from 1 to 6, and A2 is a substituent of formula (5) or (6) below.
In formulas (3) to (6), each X is independently a single bond or a divalent group, and Ar1 and Ar2 are 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 has charge-storing properties and, 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.
