A composite web is described for use in the manufacture of laminar batteries, the composite web comprising an elongated sheet of thermoplastic liquid impermeable electrically insulating material formed with a spaced array of apertures extending in rows across the sheet and in columns along the sheet, an electrode assembly adhered to the sheet around the peripheries of each of the apertures, each electrode assembly comprising a piece of electrically conducting electrochemically inert thermoplastic sheet material uniformly coated on one side opposite the side adjacent the elongated sheet with a layer of electrochemically active particles in a binder, and sheets of battery separator material each adhered to the elongated sheet over a different one of the electrode assemblies and confronting the electrode assembly. The separator sheet have peripheries extending beyond the boundaries of the electrode assemblies and each is secured to confronting regions of the elongated sheet by spaced strips of adhesive material.
