Abstract
A laminar battery comprising subassemblies made by laminating cellophane to a sheet of conductive plastic on which a series of metallic electrodes have been formed in a series of regions within the confines of the sheet, in which the cellophane is caused to adhere to the plastic and to the electrode patches by feeding the cellophane and the conductive plastic between nip rolls under pressure and supplying a small amount of an aqueous bonding composition containing a small amount of a water soluble bonding agent between the layers ahead of the nip in the rolls. The laminate so made is dried in air and may be rolled for storage and later assembly into batteries. Electrical cells and batteries made with the process just outlined.
