A method for forming cermet electrodes for alkaline accumulators consists in 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 electrolte. The band stock is assembled together with the counterelectrode and insulated from it. An apparatus for carrying out the method of forming cermet electrodes for alkaline accumulators, according to the invention, comprises an electrolyte bath having disposed in it a spool upon which are simultaneously wound a band stock and a counterelectrode insulated from each other. The width of the spool is 10 to 15% larger than the widths of the band stock and the counterelectrode. The band stock and the counterelectrode are axially offset relative to each other during winding. The heads of the spool are insulated from each other and formed with openings for accommodating contact therminals in them.
