ABSTRACT:
A method of forming cermet electrodes for alkaline accumulators, includes the step of winding a band stock together with a counterelectrode into a roll, connecting the ends of the band stock and the counterelectrode to the opposite poles of a power source, and forming cermet electrodes by anode and cathode polarization of the band stock in an electrolyte, the band stock being assembled together with the counterelectrode and insulated therefrom.
An apparatus for carrying out the method of forming cermet electrodes for alkaline accumulators, according to the invention, comprises an electrolyte bath having disposed therein a spool onto which are simultaneously wound a band stock and a counterelectrode insulated from each other; the width of the spool being 10 to 15% larger than those of the band stock and the counterelectrode, the band stock and the counterelectrode are axially offset relative to each other during winding, and the heads of the spool being insulated from each other and formed with openings for accommodating therein contact terminals.
