The invention relates to a preparation method of lithium titanium negative electrode composite material for lithium ion battery. In the invention, Li soluble compound and Ti soluble compound are taken as lithium source and titanium source, high polymer compound is added, reaction is carried out by sol-gel method, sintering atmosphere is controlled, and sintering is carried out to obtain the composite material. The method not only can prepare nano crystalline with favourable dispersity and can prepare pyrolytic carbon evenly distributed at the periphery or on the surface of granules and obviously improves conductivity of product. The lithium titanium negative electrode material prepared by the method shows excellent multiplying power performance and is applicable to power battery.
