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.
