英文摘要TiO2 is a latent anode material for rechargeable lithium batteries. Our simulation models, basing lepidocrocite and 2-MnO2 type TiO2 were investigated by density functional theory (DFT). The key issues are focused on the lithium insertion sites, electronic structures, and the conducting paths of Li+ ions. Our calculated data indicate the calculated voltage of 2-MnO2 type TiO2 is higher than that of lepidocrocite type TiO2. The Li+ ion migration energy barrier of lepidocroeite type YiO2 along the 1 0 0 direction (0.45 eV) is lower than that of along the 110 direction (0.57 eV). The energy barriers of 2-MnO2 type TiO2 to move a Li+ ion among the adjacent embedded sites (16c or 8a sites) is 0.68 eV.
