Sheet-shaped polymer secondary battery of layer built type
First Claim
1. A sheet-shaped polymer secondary battery of layer built type characterized by being a laminate of a plurality of sheet-shaped unit cells, each of which comprises the following elements (a) to (c):
- (a) a positive electrode made of a film-shaped polymer having conjugated double bonds and provided with a thin metal layer at one side of the surface of the film-shaped polymer and capable of reversibly doping and undoping negative ions,(b) a negative electrode meade of a film-shaped polymer having conjugated double bonds and provided with a thin metal layer at one side of the surface of the film-shaped polymer and capable of reversibly doping and undoping positive ions, and(c) an insulating porous separator supporting a dopant-containing electrolyte and existing between the positive electrode and the negative electrode so as to be adjacent a side of each of the positive and negative electrodes not having said thin metal layer thereon, and wherein adjacent unit cells of the plurality of unit cells are laminated such that the thin metal layer at the one side of the surface of the positive electrode of one unit cell contacts the thin metal layer at the one side of the surface of the negative electrode of the adjacent unit cell.
