The invention provides an element-doped SiOx negative electrode composite material as well as a preparation method and application thereof. According to the element-doped SiOx negative electrode composite material, the content of SiOx is 30 percent to 80 percent, the content of carbon is 20 percent to 70 percent and the content of doping elements is 5 percent or lower; the average diameter of the composite material is 3mu.m to 25mu.m, (D90-D10)/D50 is more than or equal to 1.5 and smaller than or equal to 2 and the BET specific surface area is (8+/-5)m<2>.g<-1>. The doping element is one or more of the following elements: boron, nitrogen, phosphorus, sulfur, lithium, sodium, potassium, magnesium, aluminum, zinc, copper and tin; preferably, the doping element is a combination of non-metal elements and metal elements, such as a combination of the boron and lithium, the boron and zinc, the boron and copper, the nitrogen and aluminum, the boron, aluminum and lithium, and the boron, copper and lithium, preferably, the combination of the boron, aluminum and lithium.
