PURPOSE:To enable large current charge and discharge with a solid electrode composition, by a method where the composition contains pi-electron conjugated system conductive high polymer powder, a specified copolymer, lithium salt, and propylene and/or ethylene carbonate. CONSTITUTION:Copolymer of acrylonitrile and methyl acrylate or methyl metaacrylate is dissolved in at least either of propylene carbonate dissolved with lithium salt such as lithium iodide and ethylene carbonate, to form a solid electrolyte 6 in a gel state. The electrolyte 6 has high affinity to pi-electron conjugated system conductive high polymer powder such as polyaniline, and diffuses the powder into a solid electrode composition 1 uniformly, forming low polarization electrode/electrolyte surface, and acting as bonding agent, to provide the composition 1 with good mechanical strength and workability. |
