    en.wikipedia.org/wiki/Nickel–metal_hydride_battery

    A nickel–metal hydride battery (NiMH or NiMH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
