Electrodes for primary and secondary batteries are produced by mixing a comminuted active compound with a comminuted metallic support material and then sintering the mixture under a pressure sufficient to allow the metallic particles to cohere in a temperature range of thermal stability of the active compound. The metallic support materials here specifically considered include nickel, silver, zinc and copper. The active materials include nickel fluoride, copper fluoride, silver sulfate and mercuric oxide in the case of positive electrodes as well as cadmium fluoride, zinc oxide, zinc sulfate and zinc phosphate in the case of negative electrodes. |
