Laminar cells and methods for making the same

DETAILED DESCRIPTION Having thus described the invention, what is claimed is: 1.
In an electrical cell, the combination comprising a thin sheet of ion permeable separator material; a first electrolyte permeable layer of active electrode particles held together with a polymeric binder on said separator sheet; said first layer having aqueous electrolyte distributed therein; a layer comprising a dispersion of carbon particles in aqueous electrolyte on said first layer, and a conductive plastic sheet over and in contact with said second layer.
2.
In an electrical cell, the combination comprising a thin separator sheet of regenerated cellulose, a first electrolyte permeable layer of active electrode particles held together with a polymeric binder on said separator sheet, said first layer having aqueous electrolyte distributed therein, a layer comprising a dispersion of carbon particles in aqueous electrolyte carried on said first layer, and a conductive plastic sheet over and in contact with said second layer.

Bloom, Charles K.
Chiklis and Gordon F.
Kinsman for Electrical Cells and Batteries and Methods of Making the Same, a process is described for manufacturing a laminate of zinc and cellophane.
The process basically consists in coating the cellophane with a dispersion of zinc powder in a solution of an elastomer in an organic solvent, and then drying the coating to remove the solvent to produce a thin layer of zinc powder on the cellophane that is adhered to the cellophane by the elastomer.
