CHEMICAL SOURCE OF ELECTRIC ENERGY Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: electrodes and separator are placed into multilayer case which layers are produced from polymer film, metal cloth and insulation material. Current taps of electrodes are manufactured from metal cloth, 0.05-0.2 mm thick, are brought out through connection seam of case having thickness of 0.1 mm and are impregnated with solution of polymer material to the extent bigger than seam width. Summary thickness of polymer material at point of feed-through of current tap is greater than thickness of current tap. EFFECT: prolonged storage life, increased reliability thanks to prevention of diffusion of vapors of water and electrolyte. 3 cl, 3 dwg, 1 tbl
