PURPOSE:To decrease contact resistance with a positive mix by bonding a conductive resin sheet comprising modified polypropylene and carbon black on the inner surface of a positive case with conductive paint, and using the sheet as a positive current collector. CONSTITUTION:A conductive resin sheet 6 comprising a composite material of modified polypropylene and carbon black is bonded on the inner surface of a stainless steel positive case 1 which also serves as a positive terminal with conductive paint comprising water-glass and graphite. A positive mix 5 is brought into contact with the resin sheet 6 which serves as a current collector, and combined with a separator 4 and a negative electrode 3 comprising lithium sheet to form a flat type organic electrolyte battery. The conductive resin sheet current collector 6 is chemically stable, and contact resistance of the sheet 6 with the positive mix 5 is minimized to nearly zero by bonding them with conductive paint 7. Since the sheet has elasticity, it prevents the positive mix 5 from breakage caused by sealing pressure. |
