Method of making laminar batteries

DETAILED DESCRIPTION Having thus described the invention, what is claimed is: 1.
In the process of making a laminar battery, the steps of extruding a slurry electrode onto a central region of the surface of a conductive plastic substrate, adhering a separator to a first side of a laminated frame of larger area than the separator and formed with a central opening adapted to register with and receive said electrode with the separator extending over said opening and beyond the border of said opening and the frame having border portions extending beyond the border of the separator, said frame being a laminate of two heat activatable thermoplastic adhesive materials, a first of said materials on said first side of the frame being adhesively activatable at a first temperature below the temperature at which a second of said materials is adhesively activatable under the same conditions of applied pressure and duration of heating, said separator being adhered to said first side of said frame by heat and pressure for a time sufficient to activate said first material but not said second material, placing said frame and said separator adhered thereto over said electrode and conductive plastic substrate with said electrode within said opening and said separator in registry and in contact with said electrode and extending beyond the borders of said electrode and said first side of said frame being in contact with said conductive plastic substrate beyond the borders of said separator, and adhering said frame to said conductive plastic by the application of heat and pressure for a time sufficient to activate said first material but not said second material.
2.
The process of claim 1, further comprising the steps of extruding a quantity of gel electrolyte into the opening in said frame over the separator, placing a conductive plastic intercell conductor having a second electrode formed over a central region of a first surface thereof corresponding in size and shape to said slurry electrode over said frame with said first side of said intercell connector in contact with said second material of said frame and said second electrode in contact with said gel electrolyte, and adhering said intercell connector to said frame by heating said intercell connector under pressure to a temperature sufficient to bond said intercell connector to said frame while maintaining said first side of said frame below the temperature at which said first material would flow
