The invention is applicable to the technical field of lithium batteries and provides a tungsten-doped boride-coated lithium battery anode material and a preparation method thereof. Firstly, tungsten source is dissolved in water, sprayed onto a mixed material of a ternary precursor and lithium source and then stirred to obtain a dried material; the dried material is placed and baked in a saggar toobtain a tungsten-doped ternary anode material; finally, metal boride is added to the tungsten-doped ternary anode material, stirred uniformly and sintered at a certain temperature to obtain the tungsten-doped boride-coated lithium battery anode material. According to the tungsten-doped boride-coated lithium battery anode material, the synergistic effect between tungsten doping and the metal boride takes full advantage of the tungsten doping and the metal boride, the tungsten doping can significantly inhibit grain growth and shorten the transmission distance of Li+, MgB2 as a superconductor has fast ion transmission properties, and the tungsten doping and the metal boride improve rate capability of the tungsten-doped boride-coated lithium battery anode material. Meanwhile, the boride coating can inhibit the reaction between the surface of an electrode material and electrolyte, thereby improving the safety performance and cycle stability of the tungsten-doped boride-coated lithium battery anode material.
