Size-controlled hydrothermal synthesis and electrochemical behavior of orthorhombic LiMnO2 nanorods Original Research Article

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-LiMnO2 nanorods was determined by that of γ-MnOOH precursors, which could be deliberately controlled. The electrochemical performance of o-LiMnO2 nanorods was characterized via galvanostatic tests, which suggested that the size of as-obtained products played an important role in their electrochemical performances.
