The semicircle of the intermediate frequency region is related to the charge transfer process of the Li-ion cell, and the value of semicircle's diameter is regarded as the charge transfer resistance [R.sub.ct].

The charge transfer is the electron exchange between ions in the crystal activated by photons, which may occur between metal cations (M-M), or between [O.sup.2-] and a metal cation.
As can be found from Table 3, the energy gap of the anatase Ti[O.sub.2] (101) surface dropped from 1.948 eV to 1.110 eV after [C.sub.6][H.sub.6] adsorption, to 0.775 eV after [C.sub.8][H.sub.8] adsorption, and to 0.824 eV after [C.sub.5][H.sub.8] adsorption, which illustrates that the adsorption of the three gas molecules reduced the energy gap of the anatase Ti[O.sub.2] (101) surface and improved the charge transfer ability of the anatase Ti[O.sub.2] (101) surface, causing the electron redistribution in the three systems.
