The invention relates to a highly reactive, high-purity, free-flowing and dust-free lithium sulfide powder having an average particle size between 250 and 1,500 &#x3bc;m and BET surface areas between 1 and 100 m/g. The invention, furthermore, relates to a process for its preparation, wherein in a first step, lithium hydroxide monohydrate is heated in a temperature-controlled unit to a reaction temperature between 150&#xb0; C. and 450&#xb0; C. in the absence of air, and an inert gas is passed over or through it, until the residual water of crystallization content of the formed lithium hydroxide is less than 5 wt. % and in a second step, the anhydrous lithium hydroxide formed in the first step is mixed, overflowed or traversed by a gaseous sulfur source from the group consisting of hydrogen sulfide, elemental sulfur, carbon disulfide, mercaptans or sulfur nitrides.

Highly reactive, dust-free and free-flowing lithium sulphide and method for the production thereof

The invention relates to a process for recovering lithium from lithium-sulfur accumulators, wherein the accumulators are discharged, shredded, and pre-cleaned by sieves or screens to separate housing and electricity collector parts, the remaining material is dispersed in an aqueous medium, resulting in formation of a lithium sulfide containing solution from which insoluble components are removed by filtration, and the electrolyte is removed by phase separation, followed by a process for separation of the lithium from the lithium sulfide-containing solution.
