Nickel metal hydride (NiMH) batteries are cheap, rechargeable and perform well in high-drain electronic devices.

Definition: Metal hydrides are metals which have been bonded to hydrogen to form a new compound. Generally the bond is covalent in nature, but some hydrides are formed from ionic bonds. Most hydrides behave as reducing agents in chemical reactions. Nickel metal hydride (NiMH) batteries rely on hydrides of rare earth intermetallic compounds, such as lanthanum or neodymium bonded with cobalt or manganese.
