In my understanding of nickel electroplating, nickel is used as the anode and it is also dissolved in an electrolyte to form nickel ions, which eventuallly deposits onto the cathode.

I don't know the chemical composition of Nickel Metal Hydride or its chemistry other than it contains nickel. Can Nickel Metal Hydride salvaged from discarded NiMH batteries be used in the electroplating process? Could it be used as an anode or at least used in the electrolyte solution?

  • $\begingroup$ It is not Nickel metal hydride, it is Nickel - metal hydride. Nickel itself is mostly in form of hydrated oxide gels. All in concentrated potassium hydroxide. $\endgroup$ – Poutnik Nov 5 '19 at 18:54
