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.
