Transition metal oxide particles encapsulated in nanostructured lithium titanate or lithium aluminate, and the use thereof in lithium ion batteries

A process for producing a coated transition metal oxide involves subjecting a transition metal oxide and a pyrogenically produced lithium titanate and/or pyrogenicaliy 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.
