Process for making laminar batteries

Patent ·
OSTI ID:5046740
This patent describes the process of making laminar cells, which consists of perforating a first elongated web of liquid impervious, electrically nonconducting thermoplastic material with a spaced rectangular array of apertures arranged in rows across the direction of elongation of the web and in columns parallel to the direction of elongation of the web adding patches of electrically conductive material. Each patch comprises a sheet of conductive plastic adhered to a coterminous layer of electrode particles in a binder to a first side of the first web with the conductive plastic side of each patch in contact with the borders of a different one of the apertures to form a spaced rectangular array of the patches on the firs web. A piece of separator material is adhered to the first web over each of the patches on the first side of the first web, placing spaced elongated strips of metal on the first web on a second side of the first web opposite the first side, the metal strips being aligned with and each overlying a different one of the columns.
