METHOD FOR MANUFACTURING OF NANOSIZED POWDERS FOR LITHIUM TITANATE-BASED COMPOUND Russian patent published in 2015 - IPC C01G23/00 C01D15/00 C01B31/02 C04B35/462 H01M4/485 H01M4/583 B82B3/00 B82Y30/00

Abstract RU 2538254 C1

FIELD: electricity.

SUBSTANCE: method for manufacturing of nanosized powders for Li₄Ti₅ O ₁₂/C lithium titanate-based compound includes mixing of titanium dioxide, lithium carbonate and starch and thermal treatment of the obtained mix until material is received with 100% spinel structure. Lithium carbonate is taken in 10÷15 wt % excess from stoichiometrically-defined quantity required for receipt of Li₄Ti₅ O ₁₂ compound. Starch is introduced in quantity of 10÷20 wt % of the mixture weight. The mixture is treated thermally at temperature of 850°C during 10-15 hours.

EFFECT: invention allows reduced duration of nanopowder synthetic process with receipt of material having grain size of 60-70 nm and high values of discharge capacity.
