The present disclosure relates to a method for making an electrode material of lithium-ion batteries. In the method, a carbon source compound is dissolved into a solvent to form a liquid phase solution. A number of titanium dioxide particles are provided and are dispersed into the liquid phase solution. The carbon source compound is pyrolyzed, thereby forming a number of carbon coating titanium dioxide particles. A lithium source solution is provided. The lithium source solution and the carbon coating titanium dioxide particles are mixed, according to a molar ratio in a range from about 4:5 to about 9:10, of lithium element to titanium element, thereby forming a sol. The sol is spray dried to form a number of precursor particles. The precursor particles are heated to form a lithium titanate composite electrode material.
