Nickel Metal Hydride Batteries
Metal hydride alloy may serve as the negative electrode in an alkaline battery because of the capacity to absorb and desorb hydrogen. Unlike other alkaline battery systems, nickel-metal hydride batteries are composed of materials that are not harmful to the environment. Also, the performance of nickel-metal hydride batteries is superior to that of conventional alkaline battery systems.
Nickel-metal hydride batteries are an important component in hybride vehicles and zero emission vehicles.
