PURPOSE:To obtain a battery with a long life whose retaining performance of an electrolyte is high by arranging a glass fiber body on the front and rear of a fine porous film made of synthetic resin with acid resistance and heat resistance and integrating them. CONSTITUTION:Fine glass fiber bodies 2 and 3 are arranged on the front and rear of a fine porous film 1 made of synthetic resin with acid resistance and heat resistance and the fine porous film 1 and the fine glass fiber bodies 2 and 3 are integrated. For example, the fine porous film 1 includes a great number of fine pores formed by scattering a solvent of polyorefin group resin. For example, the fine glass fiber bodies 2 and 3 are obtained by combining or wearing glass fiber with narrow diameters of approximately 0.5-1.5mu in a sheet form and these fine glass fiber bodies 2 and 3 and the fine porous film 1 are integrated by using an adhesive agent. This electrolytic retaining body is provided with the capacity of non-fluidizing an electrolyte and contributes to improve battery life. |
