PURPOSE:To improve liquid-tight performance between a frame and metallic plates serving as terminals/jar by welding plastic sheet conductors, which serve as terminals/jar, with an insulating plastic frame so that a box is formed. CONSTITUTION:An insulating plastic frame 5 is welded with one plastic sheet conductor 1 by the use of heat or supersonic waves or the like so that a box is formed. Next an anode plate 4 and a separator 3 are inserted into this box and an electrolytic solution is supplied there. Next a cathode plate 2 is supplied and finally another plastic sheet conductor 1 is welded on an opening part of the frame 5 so that a complete battery is manufactured. Hence, contact between an electrode plate active material and conductive plastic plates can be made tight to improve a utility factor of the whole active material. |
