1. Nickel-cadmium accumulator sealed in a gas-tight way with porous electrodes of opposite polarity, the negative electrode being provided with a coating of a material containing an activated carbon for catalytic oxygen recombination, and an interposed porous separator, characterized in that the material containing activated carbon is rolled in, at least into one of the electrode surfaces and in an amount adequate only for a partial surface coverage, which is 0.2 to 0.8 g/dm**2 , preferably 0.4 g/dm**2 , in such a way that the electrode has a surface structure formed by islands of exposed cadmium or cadmium hydroxide and material containing activated carbon, which alternate in random distribution. |
