Nickel Metal Hydride

Nickel–metal-hydride (NiMH) is a practical replacement of Ni–Cd where anode is made of NiMH instead of Ni–Cd. Ni–MH uses positive electrodes of nickel oxyhydroxide (NiOOH) and the negative electrodes uses a hydrogen absorbing alloy instead of cadmium. The electrochemistry of the rechargeable Ni–MH battery is given below:
