Abstract
The invention provides a carbon-coated Li3VO4 lithium ion battery anode material. The anode material is prepared according to the following method: employing vanadium pentoxide, lithium carbonate and hexamethylene tetramine as raw materials, performing a hydrothermal reaction to obtain an intermediate-phase solution, then adding citric acid into the intermediate-phase solution, mixing uniformly, and drying to obtain a solid product, and sintering the solid product in a high-temperature atmosphere, so as to obtain the lithium ion battery anode material with the Li3VO4 surface coated by amorphous carbon. The anode material is granular, and has the particle size of 90-120 nm. The carbonization effect of citric acid is utilized for fining Li3VO4 particles and uniformly coating the particle size with a carbon layer. The synthetic technology simple and easy to operate, and the material preparation cost is low. The prepared sample Li3VO4 is a uniform nano-particle, and has the dimension of 90-120 nm. In the obtained sample, the Li3VO4 particle surface is uniformly coated by amorphous carbon. The prepared material is high in charge/discharge capacity and excellent in cycle performance.
