796,410. Batteries. VOGT, H. Sept. 17, 1954 [Sept. 19, 1953], No. 27062/54. Class 53. A sealed alkaline accumulator is provided with electrodes of sintered foils which are separated from one another by a distance not exceeding 0.15 mm. by a layer of insulating material which may consist of porous synthetic material or of cotton, silk or filter paper impregnated with a solution of polyvinyl chloride, polystyrol or other synthetic resin resistant to the electrolyte. The separating material may be deposited on the electrode surface or made in the form of a sheet inserted between the electrodes. The electrodes may be filled with the hydroxides of cadmium and nickel and are in the form of flat sheets. One set of electrodes may project beyond the edges of the electrodes of opposite polarity and the edges of all the electrodes may be coated with insulating material. The electrodes are maintained under pressure in the casing by springs 10 as shown in plan in Fig. 6. Fig. 8 shows in plan a number of cells in an outer container 22 in which the ends 26 are stiffened to withstand internal pressure by means of plates 23, U-shaped members 24 and covering plates 25 which may be perforated to reduce the weight. The plates 23 may be prolonged upwardly and formed into carrying hooks. |
