What is a Nickel Metal Hydride Battery (NiMH)?

This battery uses Nickel and other rare earth metals as its electrodes and Potassium Hydroxide as the electrolyte. These are constructed from non-toxic metals making it environmentally friendly. These batteries do not suffer from the memory effect and has a higher capacity than NiCd batteries. However, the NiMH battery has a much shorter life span than NiCd and Li-Ion batteries.
