Organic solvent battery

Abstract

Abstract PURPOSE:To improve the electrolyte-holding ability of a separator, and prevent increase of the internal resistance and interruption of the electric-discharge reaction by using as the separator, a nonwoven fabric consisting of a glass fiber and a complex fiber which is prepared by coating part of polypropylene fiber with polyethylene. CONSTITUTION:In a positive can 1 made of a stainless steel or a metallic plate, a positive mixture 2 principally consisting of a positive active material such as manganese dioxide or carbon fluoride is installed. A negative terminal 3 is attached to the positive can 1, with a gasket 4 interposed between them. A negative active material 5 made of lithium metal is pressed and fixed upon the inner wall of the terminal 3. A separator 6 made of a nonwoven fabric, which consists of a glass fiber with a diameter of 0.1-1.0mum and a complex fiber prepared by coating part of polypropylene fiber with polyethylene, is situated between the positive mixture 2 and the negative active material 5. An organic solvent electrolyte which is prepared by dissolving lithium perchlorate, lithium borofluoride or the like into propylene carbonate, 1,2-dimethoxyethane or the like is poured into such a battery.
