摘要	A lithium-rich manganese-based cathode material Li1.2Mn0.54Ni0.13Co0.13O2 is restricted by the first charge and discharge efficiency and the cycle retention rate. In this paper, the effects of different drying temperatures on the comprehensive properties of Li1.2Mn0.54Ni0.13Co0.13O2 materials in sol-gel method were studied systematically. Through XRD, SEM, TEM, and electrochemical performance tests, it was found that the prepared materials have the best structure and properties when the drying temperature is 140 degrees C. The first discharge specific capacity is as high as 262.5 mAh/g in a voltage of 2.0-4.8 V. After circulating 100 cycles at a magnification of 0.5 C and 2 C, the capacity retention ratios were 80.46% and 84.14%, respectively.
