METHOD FOR PREPARING A TITANIUM AND NIOBIUM MIXED OXIDE BY SOLVOTHERMAL TREATMENT; ELECTRODE AND LITHIUM ACCUMULATOR COMPRISING SAID MIXED OXIDE

摘要

This method for preparing a titanium and niobium mixed oxide comprises the following steps: -preparation of a titanium and niobium mixed oxide in amorphous form by solvothermal treatment of at least one titanium precursor and at least one niobium precursor; -mechanical crushing of the titanium and niobium mixed oxide obtained from the solvothermal treatment; -calcination of the mixed oxide obtained after crushing.
