GALVANIC BATTERY

1,219,517. Galvanic battery. M. D. KOCHERGINSKY, L. F. PENKOVA, V. A. NAUMENKO and S. L. KALACHEV. 24 Dec., 1968 [29 Dec., 1967], No. 61235/68. Heading H1B. A cell for a galvanic battery particularly an alkaline MnO 2 -zinc cell comprises a casing which may be of plastics material, made up of two parts, a first and second anode disposed on opposite sides of a cathode and separated therefrom by diaphragms. The two parts of the casing 2 and 3 can overlap to promote hermetic sealing or each part can be provided with an extension 14 and 15 as shown in Fig. 3 to form a lap joint. Positive current collector 9 is pressed into cathode 4 and negative current collectors 12, 13 project from the cell casing through openings 10 and 11 which are sealed. The cathode may be rectangular in shape and contain a wire helix serving as the positive current collector 9. The cells may be stacked and bound together to form a battery and placed in a plastics container and then in an outer casing of cellulosic material e.g. paper.
