Marc-Christian Müller has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11542162
    Abstract: 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 ?m and BET surface areas between 1 and 100 m2/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° C. and 450° 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.

  • Patent number: 11101507
    Abstract: 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.
