METHOD FOR PRODUCING COMPOSITE ANODE MATERIAL TiNbO/C FOR LITHIUM-ION BATTERIES Russian patent published in 2023 - IPC H01M4/48 H01M4/131 

FIELD: chemical industry.

SUBSTANCE: used to create lithium-ion batteries. A method for producing a composite anode material TiNb₂O₇/C for lithium-ion batteries includes grinding, fine mixing and activation of a reaction mixture containing oxides of titanium and niobium, as well as one or more transition metal compounds, which are suppliers of substitute ions, from oxides, hydroxides or salts; heat treatment; cooling; dispersion and surface modification with carbon. The presence of substituent ions and the creation of a carbon-containing electronically conductive surface coating can improve the power characteristics of TiNb₂O₇.

EFFECT: obtaining, using mechanical activation, nanostructured composite materials based on Ti_1-xM_xNb₂O₇/C and in improving their power characteristics when used in lithium-ion batteries.
