The metal of the metal layer is advantageously selected from nickel, alloyed nickel and doped nickel.
The produced foam nickel is the ideal material for electrode substrate material of nickel-hydrogen, nickel-cadmium and nickel-zinc batteries.
The raw material for nickel comprises metal nickel.
Nickel eluent is fed into the cobalt/zinc/nickel recovery ion exchange unit to elute the nickel.
