ABSTRACT:
A secondary bipolar battery including a conductive intercell barrier having a tortuously-pathed (e.g., finned) peripheral portion outboard the cells to reduce parasitic current flow between adjacent cells around the periphery of the barrier. The battery's end electrodes have greater reactant content than the intermediate electrodes to compensate for parasitic losses. A Li/FeS.sub.2 example is detailed.
