Document Type and Number:
WIPO Patent Application WO/2003/069703
Kind Code:
A1
Abstract:
The invention aims at providing stable cells having high capacity per unit weight. The aim is attained by using an electrode containing as the active material a compound of the general formula (1) having diazine-N,N’-dioxide structure: (1) wherein x, y, x’, and y’ are each independently an integer of 0 or above; diazine rings and benzene rings may be fused alternately or at random; one of the substituents R1, R2, R3, R4, Ra, Rb, Rc, and Rd is part of the backbone or side chain of an oligomer or polymer and the others are each independently hydrogen, halogeno, or a specific group.
