Herein, size-controllable nanostructure of anatase TiO₂ with an interestingly baguetten-like morphology has been successfully prepared by a facile one-pot hydrothermal approach for the first time. When tested as a potential anode for lithium-ion batteries, the as-prepared TiO₂-0.05M exhibits impressive lithium storage performance, delivering a reversible capacity of 117.2 mAh g^-1 at 1 C after even 1300 cycles. Moreover, the results indicate that the rational nanosturcture of TiO₂-0.05M should be responsible for thus impressive lithium storage performance.

锐钛矿型TiO ₂的尺寸可控制备及其储锂性能

在此，首次通过简便的一锅水热法成功地制备了具有有趣的类似面包状形态的锐钛矿型TiO ₂尺寸可控制的纳米结构。当作为锂离子电池的潜在阳极进行测试时，所制得的TiO ₂ -0.05M表现出令人印象深刻的锂存储性能，即使经过1300次循环，在1 C时仍可提供117.2 mAh g ^-1的可逆容量。而且，结果表明，TiO ₂ -0.05M的合理的纳米结构应该负责因此令人印象深刻的锂存储性能。
