Zusammenfassung:The invention discloses an in-situ carbon-coated lithium vanadium molybdate composite material as well as a preparation method and application thereof, and belongs to the technical field of lithium ion electrode materials. The preparation method comprises the following steps: S1, weighing a molybdenum source, a vanadium source and a lithium source according to the molar ratio of Mo to V to Li in the chemical formula Li3V (MoO4) 3, adding the molybdenum source, the vanadium source and the lithium source into a ball-milling solvent, adding an additive, and then grinding to obtain a precursor mixed solution with the suspended particle size of 100nm-3mu m; s2, carrying out spray drying on the precursor mixed solution obtained in the step S1 to obtain precursor powder with the size of 4-20 microns; and S3, placing the precursor powder obtained in the step S3 in a protective atmosphere, sintering at 500-700 DEG C, and cooling to obtain the in-situ carbon-coated lithium vanadium molybdate composite material.
