539,716. Batteries ; electrolysis. HICKEY, E., and O'KEY, J. L. March 27, 1940, No. 5523. [Classes 41 and 53] The negative electrode of a storage battery comprises a conductor of a lower potential than antimony in sulphuric acid, such as copper or carbon, with negative active antimony in close contact therewith. The positive electrode comprises lead oxide or peroxide or bismuth peroxide, the electrolyte being sulphuric acid. The active antimony material c, Fig. 1, is of spongy formation associated with a copper or other conductor a enclosed in a frame b of acid-resistant material, such as lead or lead alloy, carbon, or a plastic. The negative plates may be interleaved with positive lead plates d of usual construction, or the negative plate may be. arranged centrally with positive plates on each side with their inner edges adjacent the negative plate, Fig. 2 (not shown). In another construction, Fig. 3, the antimony c and glass wool i are carried in a copper container h, the positive electrodes d being supported above, or the antimony and glass wool may be carried in a perforated celluloid container, current being taken from a copper spiral embodied in the antimony, Fig. 5 (not shown). In another construction, lead electrodes are suspended from the lid of a copper box on the inside of which the antimony is disposed by centrifuging. Lithia may be added to the active material. The negative active antimony is obtained by electrolysis of antimony oxide mixed into a paste with sulphuric acid, care being taken to prevent the evolution of hydrogen until the process is complete. Other modifications are described in the Provisional Specification. |
