Abstract: A process for producing a coated transition metal oxide involves subjecting a transition metal oxide and a pyrogenically produced lithium titanate and/or pyrogenically produced lithium aluminate to dry mixing. A coated transition metal oxide is obtainable by this process; and cathode for a lithium ion battery and a lithium ion battery containing such coated particles is useful.

Abstract: The invention relates to a process for producing lithium zirconium phosphate by means of flame spray pyrolysis using as precursors lithium and zirconium carboxylates containing 5 to 20 carbon atoms, an organic phosphate, and a solvent containing less than 10% by weight water. Lithium zirconium phosphate obtainable by this process can be used in lithium ion batteries.

Abstract: The present invention relates to a method for making a transition metal oxide coated with an at least partially amorphous lithium-containing coating and a method for making an at least partially amorphous lithium-containing powder as well as the coated transition metal oxide and the lithium-containing powder obtainable by these methods. The present invention further relates to an electrode, electrolyte, or energy-storage device, such as a lithium-ion solid-state battery, comprising the coated transition metal oxide.

Abstract: Process for producing a mixed lithium transition metal oxide usable as an active positive electrode material in lithium batteries, wherein i) a transition metal oxide, and/or a transition metal hydroxide and/or a transition metal oxyhydroxide and a pyrogenically produced zirconium dioxide and/or a pyrogenically produced mixed oxide comprising zirconium are subjected to dry mixing by means of an electric mixing unit to obtain a coated precursor compound, wherein the mixing unit has a specific electrical power of 0.05-1.5 kW per kg of the coated precursor compound; ii) the coated precursor compound is mixed with a lithium containing compound; and iii) the mixture of the coated precursor compound and the lithium containing compound is heated at a temperature between 500 and 1400° C. to obtain the mixed lithium transition metal oxide.
