Abstract: In a process for producing a positive nickel hydroxide electrode for a nickel-metal hydride or nickel-cadmium storage battery a positive nickel hydroxide electrode produced in an earlier stage in the process is after-treated by introducing a saline solution into the active mass contained in an electrode carrier structure of the electrode in order to obtain a positive nickel hydroxide electrode with an improved current yield.

Abstract: A nickel-metal hydride accumulator for industrial applications has positive nickel hydroxide electrodes and, separated therefrom, negative metal hydride electrodes as well as an alkaline electrolyte surrounding the electrodes. An improved nickel-metal hydride accumulator that is in particular insensitive to influences of temperature has a thermal arrangement which increases the specific thermal capacity of the accumulator and is formed by an additional electrolyte volume, wherein the accumulator comprises a plastics material housing which receives the electrodes and the electrolyte and is provided with a pressure relief valve.

Abstract: In order to be able to produce prismatic, unsealed nickel-cadmium batteries without limiting the amount of electrolyte, the invention proposes the manufacture of an electrode system for nicad batteries under at least partial utilization of fibe- structure electrodes, for which purpose positive and negative lamellar electrodes are produced and, with separator material interlayered, stacked in alternating fashion in a defined number to form an electrode assembly. The respective equidirectional electrodes are mutually connected by means of connecting straps; the electrode assembly is pressed and positionally locked between mechanical clamping elements into a unitized, coplanar, undeformable block, under simultaneous compression of the separator material interlayered between the electrodes.
