METHOD FOR OBTAINING COMPOSITE VANADIUM TRIOXIDE / CARBON Russian patent published in 2021 - IPC C01G31/02 C01B32/15 B82B3/00 B82Y30/00 B82Y40/00 H01M4/1391 H01M4/48 H01G4/08 H01G9/42 

FIELD: chemistry.

SUBSTANCE: invention relates to a technology for producing a vanadium trioxide/carbon composite of the composition V₂O₃/C, which can be used as an effective electrode material for lithium current sources. The method of obtaining a composite of vanadium trioxide/carbon includes obtaining an aqueous solution of malic or citric acid and vanadyl hydroxide at a molar ratio equal to (0.75-2):1, drying and annealing in an inert atmosphere, while hydrothermal treatment of the resulting solution is carried out at a temperature of 160 -200°C and an overpressure of 617-1554 kPa for 12-24 hours, and annealing is carried out at a temperature of 600-700°C for 1-2 hours.

EFFECT: invention makes it possible to obtain a high quality vanadium trioxide / carbon V₂O₃/C composite due to structural stability of the product with particle morphology in the form of spheres and a core-shell structure due to an increase in the shell thickness and a uniform distribution of component particles.
