Sealed non-aqueous electrolyte cell having a casing of a sheet of laminated material
A sealed non-aqueous electrolyte cell which has a casing made of a laminated material and which inhibits deterioration in the performance of the cell attributable to a decrease in the degree of sealing. This cell is achieved by addition of an inorganic oxide fine powder which is not an active material and is accommodated together with electric energy generating elements within the casing made from a laminated material composed of a metal foil and a resin film.A polypropylene layer is disposed inside the casing and is bonded on the inner surface of the metal foil through a carboxylic acid-denatured polypropylene layer.
