摘要：
The design of Ni-rich core and Mn-rich shell is of great significance for improving the electrochemical performance of lithium-ion battery cathode materials at high voltage. The core-shell structure LiNi0.8Co0.1Mn0.1O2 (CS-NCM811) cathode materials is prepared through co-precipitation method. XRD shows that the cathode materials have alpha-NaFeO2 layered structure and SEM images show that the material has a good morphology. The elemental compositions in Ni, Co, and Mn of both the core and shell of the CS-NCM811 particles are analyzed by EDS. The electrochemical performance results show that th...
