PURPOSE:To prevent internal shortcircuiting and enhance the safety by fixing an electrode body with a sticky tape which uses a soluble adhesion agent in an electrolytic solution, or by coating with a coating agent. CONSTITUTION:A positive electrode 1 is formed by filling a core of Ti or stainless steel with a pos. electrode black mix using MnO2 as the main active substance, followed by drying. A pos. electrode lead plate 4 of the same material is spot welded to the core. A separator 3 is formed by cutting a fine porous sheet of non-woven cloth in band form, and is interposed between the pos. and neg. electrodes 1, 2, and the whole is wound spirally to produce an electrode body. The separator 3a at the exterior extremity of this electrode body is fixed to the next separator 3b by a sticky tape 6 which uses an acrylic adhesion agent soluble in electrolyte. Otherwise, the electrode body is immersed in a solution prepared by dissolving acrylic resin in a fast-drying volatile solvent and pulled up, and the solvent is volatilized, and the whole electrode body surfaces are coated with acrylic resin as binding process. A lower insulation plate 8 is installed on the electrode body, followed by insertion in a cylindrical case 9. |
