LiCrTiO-BASED MATERIAL OF ANODE IN LITHIUM-ION BATTERY BASED ON SPINEL-STRUCTURE AND METHOD OF ITS PRODUCTION Russian patent published in 2015 - IPC H01M4/131 H01M4/1391 H01M4/485

Abstract RU 2558140 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to production of anode material with spinel structure for lithium-ion storage batteries. This process comprises mixing of lithium salt Li₂CO₃, titanium (IV) oxide TiO₂ and chromium oxide (III) Cr₂O₃ in stoichiometric ratio, as carbon precursor. Mixed particles are minced in ball mill and subjected to heat processing. Starch is used as said carbon precursor. Mincing is performed in argon medium while heat processing temperature makes 800-850°C.

EFFECT: high specific capacity and reversible cycling.
