Nanometer anatase lattices with cationic vacancies, methods for their production, and uses thereof

摘要

The present application describes a process for preparing a titanium-based compound having an anatase-type structure with cationic vacancies resulting from partial substitution of oxygen atoms with fluorine and hydroxyl groups. Also described is an electrochemically active material comprising a titanium-based compound for use in a lithium ion battery electrode. The present invention relates to chemical processes that allow the preparation of nano-sized anatase particles containing controllable amounts of cationic vacancies through partial substitution of oxygen by fluorine atoms and / or hydroxyl groups, and their use in lithium battery electrodes. .
