ELECTRODE FOR BATTERY

PURPOSE:To increase the capacity of a battery and moreover to make high rate discharge possible by supporting a composite comprising conductive polymer and anionic polymer electrolyte in a porous conductor. CONSTITUTION:This electrode is prepared by supporting a composite comprising a conductive polymer (A) and an anionic polymer electrolyte (B) in a porous conductor (C). Polypyrrole and others are used as the polymer (A), polystyrene sulfonic acid anion and others as the electrolyte (B), and a felt-shaped molding made of carbon fibers formed by vapor phase deposition as the conductor (C). The composite is supported in the conductor (C) by using the conductor (C) as an anode and electrolyzing an aqueous solution containing monomers of the polymer (A) and the electrolyte (B) as an electrolytic solution to form the electrode. The electrode obtained is used in a battery using a metal such as lithium as the counter electrode.
