Lithium borohydride (LiBH₄) is an ionic ceramic compound and solid-state hydrogen storage material that belongs to the family of complex metal hydrides. It is primarily investigated in research and development contexts as a potential hydrogen storage medium for next-generation energy applications, particularly for fuel cell vehicles and portable power systems. LiBH₄ is notable among hydride materials for its exceptionally high gravimetric hydrogen content and has attracted significant attention from materials scientists and automotive engineers seeking viable alternatives to conventional fossil fuels, though practical deployment faces challenges related to thermal stability, hydrogen release kinetics, and reversibility of the storage process.
