Abstract
PURPOSE:To sharply reduce the consumption of a positive electrode active material due to the oxidation decomposition of an organic binder and the gas generation accompanying it by using at least one of chitosan and chitin for the organic binder. CONSTITUTION:At least one of chitosan and chitin which are chemically stable compounds is used for the organic binder of the positive electrode black mix of a thin cell. chitin is nitrogen-containing polysaccharide which is an important component of the skin of the arthropod, mollusk shell or the like and exists in an organism as glycoprotein and is obtained by removing protein with alkali. Chitosan is a product obtained by heating chitin in a concentrated alkaline solution or potassium-melting and deacetylating it and is the achromatic noncrystalline powder. The gas generation in the positive electrode black mix due to the oxidation decomposition of the organic binder is thereby reduced, the bulging of the thin cell is suppressed, the adhesion between a current collector and a positive electrode black mix layer can be improved.
