NiMH nickel-metal hydride cell, abbreviated NiMH, is a type of secondary electrochemical cell similar to Nickel Hydrogen cell. The NiMH battery uses a hydrogen-absorbing alloy for the negative electrode instead of cadmium. As in NiCd cells, the positive electrode is nickel oxyhydroxide (NiOOH). A NiMH cell can have two to three times the capacity of an equivalent size Nickel-cadmium battery. NiCdLi-ion.
