Abstract
The present invention provides a polymer compound for an electrode material permitting operation at low temperatures and attainment of large capacities, an electrode using the polymer compound, and a nonaqueous solution battery involving the electrode as the positive electrode thereof. The polymer compound includes a structure capable of intramolecularly forming at least one S--S bond in a single side chain of the repeating unit thereof. The S--S bond constitutes a part of a 4- to 6-membered heterocycle. The electrode includes as an electrode material the polymer compound including a structure capable of intramolecularly forming at least one S--S bond in the single side chain of the repeating unit thereof. The nonaqueous solution battery includes a positive electrode, an electrolyte and a negative electrode, and the positive electrode is an electrode including as an electrode material the polymer compound comprising a structure capable of forming at least one S--S bond in the single side chain of the repeating unit thereof.
