The invention relates to a graphene/titanium dioxide nano fiber composite material, a preparation method and applications thereof. Graphene is taken as the carrier skeleton, and nano fiber-liked titanium dioxide evenly grows on the edges and two sides of the carrier skeleton, wherein the diameter of the titanium dioxide is 6 nm to 24 nm, and the length of the titanium dioxide is 100 nm to 1000 nm. The provided preparation method is green and environment-friendly, and moreover overcomes the shortages of complicated technology, high cost, and low yield in the conventional methods. The composite material is used as the negative electrode material of a lithium ion battery. The specific capacity of the lithium ion battery is 128 mAh/g, 104 mAh/g, and 85 mAh/g, when being at 5 C, 10 C, and 20 C.
