a process is described for electrolytically producing nickel electrodes by subjecting a porous nickel structure to alternating anodic and cathodic pulses in an aqueous halide solution . the alternating pulses first anodically dissolve the nickel from the porous nickel plaque and then cathodically precipitate the nickel in the form of the hydroxide . particularly attractive is the use of a stable , simple solution , room temperature operation and the broad variation in operating conditions that still produce optimum results .
