Abstract
A method for preparing a positive electrode active material for a lithium battery consisting of a lithiated oxide comprising titanium and optionally one or more other metal elements comprising the following successive steps: a) a step of forming a precipitate comprising titanium and the optional other metal element(s) by contacting a titanium coordination complex and, if necessary, at least one salt of the other metal element(s) with an aqueous medium; b) a step of recovering the precipitate thus formed; c) a step of calcining the precipitate in the presence of a lithium source.
