The usual TiO2 anatase crystal is dominated with (101) face, due to its thermodynamic stability, but presently the (001) face is the other point of interest, because it is supposed to be more active for Li-insertion than (101) face. The fluorine terminated TiO2 anatase with a large proportion of (001) faces was thermally treated to be F-free and characterized by common methods. There are improved electrochemical properties after calcination. The electrochemical measurements of TiO2 anatase with (001) faces indicate the better Li-ion insertion/extraction behaviour than the ordinary anatase crystals with dominating (101) faces.
