a compound of hydrogen with a more electropositive element
Inorganic compound of hydrogen with another element. Three common types are differentiated by their bonding. In saline (ionic) hydrides (see ionic bond), the hydrogen is an anion, H^-, and behaves like a halogen. Saline hydrides such as sodium hydride (NaH) and calcium hydride (CaH2) react vigorously with water, giving off hydrogen gas (H2), and are used as portable sources of it. Metallic hydrides, such as titanium hydride (TiH2), are alloylike materials (see alloy) with some properties of metals, such as luster and electrical conductivity. Covalent hydrides (see covalent bond) are mostly compounds of hydrogen and nonmetallic elements; they include water, ammonia, hydrogen sulfide (H2S), and methane. In polymeric hydrides, the hydrogen forms bridges between other atoms (e.g., hydrides of boron and aluminum). Those hydrides give off large amounts of energy when burned and may be useful as rocket fuels

nickel-metal hydride battery
(Elektrik, Elektronik) A nickel-metal hydride cell, abbreviated NiMH, is a type of rechargeable battery similar to the nickel-cadmium 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 battery can have two to three times the capacity of an equivalent size nickel-cadmium battery. Compared to the lithium-ion cell, the volumetric energy density is similar but self-discharge is higher
