Runquist, J A; Howard, W G; Berberick, D R

A laminar battery is described having a substantially flat, thin metal case containing an active laminar anode element and a pair of laminar porous cathode elements oppositely disposed with respect to the anode so that the inner laminar surfaces of the porous cathode elements are disposed adjacent opposite laminar surfaces of the anode element. The outer laminar surfaces of the cathode elements are disposed adjacent the inner sides of the flat metal case, and porous separator means are interposed between the adjacent anode and porous cathode laminar surfaces, all of the elements being adapted and arranged into a laminar structure within the flat metal case. Liquid cathode-electrolyte means are disposed in the metal case and in contact with the elements. Electrically conductive means, insulated from the case, contact the anode element and extend exteriorly of the case.
