Abstract

PURPOSE:To hold a large quantity of an electrolyte between a negative electrode and a positive electrode and to improve its discharge performance, by interposing between both electrodes a separator consisting of an inner layer of synthetic fibers and a pair of outer layers made of natural fibers and sandwiching said inner layer. CONSTITUTION:On each surface of a layer 3 of synthetic fibers such as vinylon fibers, is superposed a surface layer 4 of natural fibers such as viscose rayon fibers to form a separator 5 of an integrally multi-layered structure. The separator 5 is placed on the upper surface of a positive electrode mixture 2. The circumferential edge of the separator 5 is fixedly held by the lower surface of an insulator packing 6 inserted in a metal can 1 and having an L-shaped cross-section. Owing to the multi- layered structure of the separator, any insufficient elasticity of the surface layers of natural fibers, which would be caused as a result that the surface layers are susceptible of becoming brittle by the attack of the electrolyte, would be supplemented by the inner layer of the anti-alkaline synthetic fibers, thereby holding a great quantity of the electrolyte between the negative and positive electrodes and improving the discharge characteristics of the battery.
