以γ-MnOOH纳米棒为前驱体，在180°C水热条件下通过同晶离子交换法制备了大量均匀的正交LiMnO 2（o-LiMnO 2）纳米棒。所制备的o-LiMnO 2纳米棒的尺寸取决于γ-MnOOH前驱体的尺寸，可以人为控制。通过恒电流测试对o-LiMnO 2纳米棒的电化学性能进行了表征，结果表明，产物的尺寸对其电化学性能有重要影响。
Large amount of uniform orthorhombic LiMnO2(o-LiMnO2) nanorods was fabricated by a hydrothermal route in 180°C using γ-MnOOH nanorods as precursors through an isomorphous ion exchange process. The size of as-obtained o-LiMnO2nanorods was determined by that of γ-MnOOH precursors, which could be deliberately controlled. The electrochemical performance of o-LiMnO2nanorods was characterized via galvanostatic tests, which suggested that the size of as-obtained products played an important role in their electrochemical performances.
