The present invention discloses a method to modify the titanium oxide based anode materials by coating a thin layer of AlF3 on the particle surface and the excellent battery performance for the thus obtained surface-modified titanium oxide based materials. This method is simple and cost effective. The key aspect of the present invention is to keep the AlF3 coating at low content particularly between 0.1% and 10% and more particularly between 1% and 5%. The thin AlF3-coating layer significantly improves the power performance, capacity retention at elevated temperatures and long term cycle life of the lithium-ion batteries using these surface-modified anode materials.
