METHOD OF PREPARING HIGH-DISPERSITY LITHIUM-VANADIUM OXIDE LiVO Russian patent published in 2002 - IPC

FIELD: inorganic compounds technology. SUBSTANCE: in order to obtain vanadium and lithium compounds suitable for lithium-ion accumulators or catalysts, mixture of starting lithium and vanadium compounds are subjected to mechanical activation via grinding on centrifugal-planetary mills. Power supplied to activator varies between 10- 50 W/g, activation time between 1-10 min, weight ratio of reactants to activation bodies 0.025:0.05, and Li/V atomic ratio (1.0-1.1): 3. If needed, activated mixture is subjected to heat treatment at 200-400 C for 1-4 h. EFFECT: enabled preparation of high-activity lithium- vanadium oxide. 3 cl, 2 dwg, 7 ex
