The invention relates to a modification method for a tungsten-containing compound coated positive electrode material of a lithium ion battery, and belongs to the technical field of a manufacturing process of a lithium ion battery material. According to the modification method, a tungsten-containing compound, a hydroxide precursor and lithium carbonate are subjected to wet ball milling and mixing by adopting a one-step method; and the mixture is subjected to vacuum drying and then a high-temperature solid-phase reaction to obtain the tungsten-containing compound coated and modified LiNi<0.6>Co<0.2>Mn<0.2>O<2> material. By virtue of the method, the cycle performance and the rate capability of the positive electrode material of the lithium ion battery are effectively improved; and meanwhile, the preparation method is low in cost and simple to operate.
