Abstract

PURPOSE:To prevent internal shortcircuiting effectively by forming a separator from an alternate lamination of porous high-density films with resistance against electrolyte and unwoven cloths with two or more layers, and by arranging unwoven cloths on the negative pole side. CONSTITUTION:Alternate lamination of two or more unwoven cloths and films are formed, wherein the unwoven cloths 5 are of glass fiber etc., having a thickness of 60-200mum, a density of 0.3-0.45g/cm<3>, while the films are of polyethlene etc., having a thickness of 25-100mum and a density of 0.5-0.6g/cm<3>, and the unwoven cloths 5 are arranged on the negative pole 1 side. The negative pole is made of metal Li etc., while the positive pole is of an electroconductive polymer such as polyacetylene, and the solution used shall for ex. be LiClO4, and the solvent 1,2-dimethoxyethane, whereto triethyl amin etc., is added as a stabilizer. According to this arrangement, eventual production of Li dendrite on the negative pole 1 will not necessarily lead directly to internal shortcircuiting, that should prolong the cycle life of a Li secondary battery.
