Lithium-beryllium hydrides: the lightest reversible metal hydrides

Lithium-beryllium hydrides are a new group of metal hydrides for hydrogen s torage. They show the highest reversible hydrogen capacity (more than 8 wt. %) of all known metal hydrides. Measurements of equilibrium pressures of th e Li-Be hydrides indicate that these materials can be used at temperatures down to 150 degrees C. Fully reversible and safe, these materials offer a n ew prospect for hydrogen storage, especially for small-scale applications w here capacity is critical. (C) 2000 Elsevier Science S.A.
