Ternary borides and borohydrides for hydrogen storage and method of synthesis

DWPI Title: Making mixed-metal ternary boride/borohydride hydrogen storage material involves mixing Ma metal source, Mb metal source, and borane adduct in hydrocarbon solvent, where Ma is metals selected from lithium, sodium, potassium and calcium
Abstract: A method and a system is provided for obtaining solid-state hydrogen storage and release in materials with at least theoretical loaded hydrogen densities of 11 wt % or greater that can deliver hydrogen and be recharged at moderate temperatures enabling incorporation into hydrogen storage systems suitable for transportation applications. These materials comprise ternary boride materials comprising certain light transition metals and alkaline or alkaline earth metals, and ideally have no or very little phase separation. A process of making these materials is also provided.
Use: Method for making mixed-metal ternary boride/borohydride hydrogen storage material used in hydrogen-based energy storage system for powering electric vehicle.
Advantage: The mixed-metal ternary boride/borohydride hydrogen storage material is free of phase segregation.
Novelty: Making mixed-metal ternary boride/borohydride hydrogen storage material involves mixing Ma metal source, Mb metal source, and borane adduct in hydrocarbon solvent, where the Ma is metals selected from lithium, sodium, potassium, magnesium, and calcium, and Mb is metals selected from titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc, removing excess solvent and liquid by-products by drying and applying a vacuum.
