US 8,197,707 B2 · Lithium-porous metal oxide compositions and lithium reagent-porous metal compositions

Abstract

The invention relates to lithium metal/porous metal oxide compositions. These lithium metal compositions are prepared by mixing liquid lithium metal with a porous metal oxide in an inert atmosphere under exothermic conditions sufficient to absorb the liquid lithium metal into the porous metal oxide pores. The lithium metal/porous metal oxide compositions of the invention are preferably loaded with lithium metal up to about 40% by weight, with about 20% to 40% by weight being the most preferred loading. The invention also relates to lithium reagent-porous metal oxide compositions having RLi absorbed into a porous oxide. The preparation and use of these compositions are also described.
