1. A complex hydride battery comprising:
a cathode comprising a metal hydride according to the formula (MHx) where M is a metal and X further represents an oxidation state of the metal; an anode comprising a lithium metal; and an electrolyte comprising a complex hydride, the complex hydride is selected from the group consisting of LiAlH4, NaAlH4, KAlH4, Ca(AlH4)2, Mg(AlH4)2, LiBH4, and NaBH4, dissolved in an organic solvent selected from the group consisting of THF, ethers, amines and mixtures thereof to allow for the transport of the complex hydride's corresponding hydride ions selected from the group consisting of AlH4 ions and BH4 ions.
