PURPOSE:To reduce the thickness of a pos. electrode part to a great extent by making a current collector from an Al foil with ample ductility, and forming a pos. electrode black mix in such a composition as attaching to the Al foil. CONSTITUTION:As pos. electrode active substance is used vanadium pentoxide V2O5, and 2 thru 15 parts electroconductive agent is mixed with 100 parts V2O5. These pos. electrode black mix, electroconductive agent, a small amount of binder, plasticizer, and solvent are mixed together and shaped into a sheet by extrusion molding. The solvent, binder, and plasticizer are pyrolyzed by raising the temp. in steps at the driving process, and a sheet from black mix for pos. electrode is achieved. This is attached by pressure to a pos. electrode current collector consisting of Al foil. The thickness of this Al foil shall be below 50mum. |
