چکیده انگلیسی
H2Ti12O25 nanorods are successfully prepared via hydrothermal reaction following heat treatment at 260 °C. The D50 value and surface area of H2Ti12O25 nanorods are 0.186 μm and 35.0637 m2 gâ1, respectively. For comparison, Bulk-H2Ti12O25 are also prepared by milling assisted soft-chemical method, and the D50 value and surface area of Bulk-H2Ti12O25 are 0.274 μm and 4.3213 m2 gâ1, respectively. The electrochemical tests show H2Ti12O25 nanorods deliver higher reversible capacity of 191.3 mAh gâ1 (1C) after 100 cycles, 150.5 mAh gâ1 (10C) and 132.1 mAh gâ1 (20C) after 200 cycles, while for Bulk-H2Ti12O25, its reversible capacity is only 171.2 mAh gâ1 (1C) after 100 cycles, 113.7 mAh gâ1 (10C) and 83.3 mAh gâ1 (20C) after 200 cycles. Meanwhile, H2Ti12O25 nanorods exhibit better rate performance at all rates compared with Bulk-H2Ti12O25. The higher discharge/charge capacity and cycling stability at high discharge/charge rate powerfully suggests that H2Ti12O25 nanorods hold great potential as high rate anode material for electric vehicles and hybrid electric vehicles.
