Abstract

A laminar triplex structure for use in the manufacture of electrical cells and batteries, cells and batteries made therefrom, and methods of making the same. The laminate comprises a thin flat sheet of separator material, a layer of metallic particles on one surface of the separator sheet and adhered thereto with a binder, and a layer of conductive plastic adhered to the layer of metal particles. The laminate is made by the process of coating a dispersion of metal particles in a solution of a polymeric binder in an organic solvent over the separator, drying to remove the solvent, coating over the dried metal layer with a dispersion of conductive particles in a solution of a polymer in an organic solvent, and drying to remove the solvent.
