摘要

682,748. Batteries. HEROLD, V. Feb. 22, 1951 [Feb. 28, 1950 ; June 9, 1950], No. 4337/51. Class 53. An accumulator electrode consists of porous sintered metal impregnated with active material and a compound of titanium. If the sintered metal serves as the active material, for example iron, it is impregnated with a titanium salt and then with caustic alkali to precipitate titanium hydrate. If the sintered metal is inactive, for example nickel or iron rendered passive, it is first impregnated with titanium and then with electrochemically active substances such as cadmium or iron. Alternating layers of titanium and active material may be deposited in the sintered body by successive impregnations. The titanium and active material may also be precipitated simultaneously as hydrates in the porous body and the active material may consist of a mixture of cadmium and iron hydrates. In an example, a porous sintered metal plate is immersed in an aqueous solution of the chlorides of cadmium, iron, and titanium and then subjected to electrolysis in a bath of caustic soda to reduce the salts to hydrates. Specification 339,645, [Class 53], is referred to.
