The process makes use of a corrosive action in a special alkaline electrolyte in order to produce electrochemically active masses from a metallic phase, preferably nickel, by anodic oxidation. The corrosion products or active masses are formed in the pores of a sintered electrode (or porous fibrous electrode). The novel electrolyte is composed of a small amount of alkali-metal hydroxide, specifically potassium or sodium hydroxide solution, and also of barium or strontium hydroxide and hydrogen superoxide. During the production of the active mass, for example of the nickel oxide hydrate, no harmful foreign anions are incorporated in the structure of the mass, and this promotes an improvement in the capacity. The process renders earlier precipitation and impregnation procedures superfluous. In addition, the production process is more environmentally friendly and makes cost savings possible. |
