METHOD FOR OBTAINING A COMPOSITE OF VANADIUM TRIOXIDE/CARBON Russian patent published in 2018 - IPC C01G31/02 C01B32/15 B82B3/00 B82Y30/00 H01M4/48 

FIELD: biochemistry.

SUBSTANCE: invention can be used to produce electrode material of lithium current sources. Method for the preparation of a composite vanadium trioxide/carbon V₂O₃/C involves the dissolution of a carboxylic acid in water, addition of a vanadium oxide compound, drying and subsequent annealing. Apple or citric acids are used as a carboxylic acid. Vanadyl hydroxide is used as the vanadium oxide compound. Molar ratio of apple or citric acids:vanadyl hydroxide is (0.75–2):1. Annealing is carried out in an inert atmosphere at a temperature of 490–550 °C for 1–2 hours.

EFFECT: invention makes it possible to exclude the use of harmful or poisonous ingredients, to ensure the production of a product with a uniform distribution of the particle components, to reduce the agglomeration of particles, to shorten the duration of the process.
