Abstract:Dual-phase Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf>-TiO<inf>2</inf>nanocrystallines were prepared by a solvothermal process. The product exhibited initial discharge capacities of 315 and 230 mAh/g at the discharge rates of 0.1 and 1 C, respectively. After 80 cycles, the Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf>-TiO<inf>2</inf>nanocrystallines retained 83% and 87% of its initial discharge capacities at the 0.1 and 1 C rates, respectively. The high electrochemical performance indicates that dual-phase Li<inf>4</inf>Ti<inf>5</inf>O<inf>12</inf>-TiO<inf>2</inf>nanocrystallines are highly promising anode materials for lithium ion battery applications. © 2014 Elsevier B.V.<br/>
