Abstract
An object of the present invention is to provide a battery which is high in capacity density and superior in stability. An electrode containing a compound having a diazine-N,N'-dioxide structure shown by a general formula (1) described below as an electrode active material is used, where x, y, x′, and y′ independently shows integer numbers of 0 or more respectively, and the order of condensation of diazine rings and benzene rings may be alternate or random. One of substituents R, R, R, R, R, R, R, and Rshows a part of main chain or side chain of oligomer or polymer, and the other independently shows hydrogen atom, halogen atom, or a specific group.
