  title = {Hydrogenation effects on the lithium ion battery performance of TiOF<sub>2</sub>},
  abstract = {<p>Hydrogenated titanium oxyfluorides (TiOF<sub>2</sub>) nanoparticles were synthesized via one-pot hydrothermal method and subsequent hydrogenation treatment. As anode materials for lithium ion batteries, the hydrogenated TiOF<sub>2</sub> showed a superior rate performance compared to the pristine TiOF<sub>2</sub>. A charge capacity of 118.4&nbsp;mA&nbsp;h&nbsp;g<sup>−1</sup> was achieved at the current density of 1053&nbsp;mA&nbsp;g<sup>−1</sup> upon 150 cycles, which was 4 times higher than that of the pristine TiOF<sub>2</sub>. The rate performance of the hydrogenated TiOF<sub>2</sub> at different current densities of 42, 210, 1053, 2106, 5265, 10530, 21060 and 52650&nbsp;mA&nbsp;g<sup>−1</sup> was 2.8, 6.0, 13.2, 14.7, 21.5, 30.6, 67.9 and 483.3 times higher than those of the pristine TiOF<sub>2</sub> electrode at the corresponding rates, respectively. The remarkable improvement of the electrochemical performance was likely related to the size breakdown in the (001) direction after hydrogenation, instead of oxygen vacancies induced better charge transfer properties.</p>},
