Nanometer Anatase Lattice with Cation Vacancies, Method of Producing It, and Its Use

摘要

The present application describes a process for the preparation of titanium-based compounds having an anatase type structure with cationic vacancies arising from a partial substitution of oxygen atoms by fluorine atoms and hydroxyl groups. Electrochemically active materials comprising the titanium-based compounds for use in lithium-ion battery electrodes are also described.
