Laminar cells and batteries
First Claim
1. A battery comprising a stack of laminar cells terminated at one end by an end terminal formed with a pocket, said end terminal comprising an external metal collector sheet laminated to a sheet of conductive plastic confronting the cell components, said cells each comprising at least one electrode comprising a slurry of electrochemically active particles in an aqueous electrolyte, a second electrode, and a separator between said slurry electrode and said second electrode, in which at least the separator in the cell adjacent said pocketed end terminal comprises a layer of regenerated cellulose in contact with said second electrode and a layer of porous bibulous material over said regenerated cellulose layer and in contact with said slurry electrode to limit migration of electrolyte from said slurry electrode.

Abstract
A laminar battery comprising an end terminal formed with a pocket to accept internal components without requiring additional edge thickness in the seal area, incorporating as the separator in at least the cell immediately adjacent the pocketed end terminal a layer of cellophane together with a layer of paper on the side of the cellophane confronting the cathode.
