Novel inorganic hydride

A novel inorganic hydride compound KH KHCO3 which is stable in water and comprises a high binding energy hydride ion was isolated following the electrolysis of a K2CO3 electrolyte. Inorganic hydride clusters K[KH KHCO3]+n were identified by Time of Flight Secondary Ion Mass Spectroscopy. Moreover, the existence of a novel hydride ion has been determined using X-ray photoelectron spectroscopy, and proton nuclear magnetic resonance spectroscopy. Hydride ions with increased binding energies may be the basis of a high voltage battery for electric vehicles.
