Patent ID: 7135250

Claim:
A battery comprising: a composite mixture layer including a cathode active material formed over portions of a main surface of each of a plurality of cathode current collectors formed in substantially rectangular shapes, with non-applied portions therebetween; and wherein the composite mixture is not applied at both ends of each cathode current collector on a side of each cathode current collector opposite the main surface, wherein one cathode current collector is connected to an adjacent cathode current collector at one end portion of each cathode current collector on the side opposite the main surface through a connecting part to which the composite mixture is also not applied; and a plurality of anode current collectors formed in substantially rectangular shapes; and anode composite mixture layers including an anode active material formed over portions of both surfaces of the anode current collectors; and an anode lead is provided at one end of each anode current collector; and each cathode current collector is bent at the non-applied portion such that the anode composite mixture layers formed on both surfaces of each anode current collector are sandwiched in between one cathode composite mixture layer and another cathode composite mixture layer provided on the main surface of each anode cathode current collector with a solid electrolyte film therebetween.
