Abstract AITranslate

Nano-MoS2 modified lithium-rich manganese-based cathode material Li1.2Mn0.54Ni0.13Co0.13O2 was prepared by simple liquid-phase grinding method.The constant current charge and discharge test results show that the nano-MoS2 modified material exhibits excellent electrochemical cycle stability.3%MoS2 modified material has a discharge specific capacity of up to 235mA·h/g after 120cycles at 0.5C,and the capacity retention ratio reaches 88.4%,which is significantly higher than 70.1%capacity retention ratio and 153.8mA·h/g discharge specific capacity of the blank.In addition,the voltage decay of 3%MoS2 modified material is only 0.44 Vafter 120 cycles compared with the blank of 0.70 V.It can be seen that the voltage decay of the material during cycle is also significantly improved.
