Synthesis and electrochemical performance of Mo-doped LiNi_0.5Mn_1.5O₄ cathode material

ABSTRACT

The Mo-doped LiNi_0.5Mn_1.5O₄ material has been successfully synthesized by the freezing precipitation method, and the effect of different doping amounts on the properties of LiNi_0.5Mn_1.5O₄ material has been studied. Texting has included XRD, SEM, first charge and discharge curves, cycle performance, rate cycle, CV analysis, and EIS analysis. The experimental results show that the Mo-doping material shows superior performance when the doping amount is 1%, and this amount ensures the highest capacity of the sample. The capacity is 120.1 mAh g⁻¹ at 0.1 C (initial discharge), with which the particle size and the dispersion are uniform. After 50 cycles, the discharge capacity is 118.3 mAh g⁻¹ at 0.1 C, and the capacity retention rate is 98.5%. These results reveal that Mo-doped LiNi_0.5Mn_1.5O₄ contributes to the outstanding electrochemical performance of the LiNi_0.5Mn_1.5O₄.
