Abstract
Abstract High-voltage LiNi0.5Mn1.5O4 nanorods were prepared through a low-cost and environment-friendly strategy with MnO2 nanorods as manganese source. The resulting LiNi0.5Mn1.5O4 nanorods showed satisfactory rod-like morphology and obvious characteristic diffraction peaks of LiNi0.5Mn1.5O4. According to the research results of electrochemical properties, the obtained LiNi0.5Mn1.5O4 nanorods showed excellent cycling stability. When cycled at 1.0 C, this sample exhibited 125.2 mAh g−1 at the first cycle in the voltage range of 3.4–5.0 V. After 200 cycles, the satisfactory capacity of 119.8 mAh g−1 could be obtained with outstanding retention of 95.7%, which was far more advantageous than that of the LiNi0.5Mn1.5O4 particles (78.1%). Moreover, the LiNi0.5Mn1.5O4 nanorods could show a superior capacity of 93.4 mAh g−1 at 10 C, whiles the LiNi0.5Mn1.5O4 particles only exhibited 58.5 mAh g−1. These results indicated that the obtained LiNi0.5Mn1.5O4 nanorods possessed great potential and application prospect to be a promising 5.0 V cathode material.
