Japanese Patent JP2999813
Kind Code:
B2
Abstract:
PURPOSE:To increase discharge capacity by using a conductive polymer polymerized by using a compound containing nitrogen atoms as an electrolyte solvent for electrolytic polymerization and using polymerized conducting polymer as a material for the electrode. CONSTITUTION:A conductive polymer polymerized by using a compound containing nitrogen atoms as an electrolyte solvent for electrolytic polymerization is used as a material for the electrode. As the compound containing nitrogen atoms, at least one of cyclic compound having at least one nitrogen and oxygen atoms in its ring, and a group of formaldehyde derivatives is selected and used. By synthesizing the conductive polymer by electrolytic polymerization, a low molecular weight component of the conductive polymer dissolves and a high molecular weight component remains. the more amount of electrons the conductive polymer has the more excellent in its characteristic it is as an electrode material, providing an electrode capable of being charged to higher capacity.
