Summary: | The invention provides a preparation method of a nanorod negative electrode material ferric vanadate for a lithium-ion battery. The method comprises the following steps of: (1) adding a surfactant and an organic solvent to a cosolvent, and stirring the surfactant and the organic solvent to obtain a uniform emulsification system; (2) firstly adding a ferrous oxalate solution to the uniform emulsification system, stirring the ferrous oxalate solution, dropwise adding a vanadium salt solution and carrying out water bath stirring to obtain a stable and uniform microemulsion system; (3) carrying out centrifuging, washing, precipitating, filtering and drying to obtain precursor FeV(C2O4)4 powder; and (4) carrying out thermal treatment in an aerobic atmosphere to obtain the nanorod negative electrode material ferric vanadate for the lithium-ion battery. According to the ferric vanadate material obtained by the method, the initial specific discharge capacity at 0.1C can reach 1377.1mAh/g and the initial specific disc |
