| 摘 要： | LiNi0.5Mn1.5O4 was prepared by rheological method using CH3COOLi, Ni(CH3COO)2 and Mn(CH3COO)2 as raw materials. XRD and SEM results show that LiNi0.5Mn1.5O4 synthesized at 850 ℃ has cubic spinel structure with clearly defined shape and particle size of 0.2～0.4 μm. Electrochemical tests show that the LiNi0.5Mn1.5O4 presents a plateau near 4.7 V and delivers the maximum discharge capacity of 140.5 mAh·g-1. After 100 cycles, the capacity loss per cycle was only 0.015% discharged at 0.2C and the capacity retention was more than 76.3% discharged at 2.0C at room temperature and the capacity loss per cycle was only 0.32% discharged at 0.2C at 55 ℃. |
