摘要:The invention relates to a process for producing alpha lithium aluminate comprising the following steps: 1) preparing an aqueous dispersion comprising a fumed alumina, a lithium oxide precursor compound soluble in water and an alkali metal and/or an ammonium carbonate; 2) Spray drying of the dispersion prepared in step 1) to obtain a dried powder; 3) Calcining the dried powder obtained in step 2) at a temperature of from 450°C to 750°C. Lithium aluminate obtainable by this process can be used in lithium ion batteries.

权利人:6K INC
摘要:Disclosed herein are systems and methods for synthesis of submicron-scale or micron-scale single crystal cathode (SCC) material, such as NMC, using a feedstock and microwave plasma processing. Microwave plasma processing of these SCC materials provides a low cost, scalable approach. In some embodiments, advanced SCC materials may be synthesized through microwave plasma processing of feedstock materials, wherein the SCC materials may comprise at least 80% nickel. In some embodiments, the microwave plasma processing may enable synthesis of SCC materials with very short calcination.

摘要:A catalyst-free synthesis method for the formation of a metalorganic compound comprising a desired (first) metal may include, for example, selecting another (second) metal and an organic solvent, with the second metal being selected to (i) be more reactive with respect to the organic solvent than the first metal and (ii) form, upon exposure of the second metal to the organic solvent, a reaction by-product that is more soluble in the organic solvent than the metalorganic compound. An alloy comprising the first metal and the second metal may be first produced (e.g., formed or otherwise obtained) and then treated with the organic solvent in a liquid phase or a vapor phase to form a mixture comprising (i) the reaction by-product comprising the second metal and (ii) the metalorganic compound comprising the first metal. The metalorganic compound may then be separated from the mixture in the form of a solid.
