Enhanced Rate Capability and Low-Temperature Performance of LiTiO Anode Material by Facile Surface Fluorination.

A commercial LiTiO material was modified by NHF using a facile and dry method at a low temperature in air. X-ray diffraction reveals that the fluorination did not change the bulk structure of LiTiO. X-ray photoelectron spectroscopy demonstrates that LiF was formed at the surface and Ti was partially changed into Ti.
