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.
