Lithium ion battery has the advantages of high working voltage, good cycling performance andenvironmental friendliness. It is widely used in various battery energy storage devices. High nickelternary positive electrode materials with α-NaFeO2 type layered crystal structure have become the focusof research in recent years due to their high energy density and good cycling performance. In this paper,LiNi0.8Co0.1Mn0.1O2 high-nickel ternary material was prepared by hydrothermal method, and theproperties of the material were determined by phase analysis and electrochemical analysis. and theinfluence of sintering temperature on the morphology and structure and electrochemical performance ofthe ternary-type material was investigated. The results show that the optimal process conditions for theprecursor mixed lithium sintering are divided into two steps: the first step is calcined at 500°C for 6h,and the second step is calcined at 800°C for 8h. Under these conditions, the LiNi0.8Co0.1Mn0.1O2 has thebest morphology and the highest crystallinity, and has a specific capacity of 198.5 mAh·g-1at the rate of0.2 C. After 100 charge and discharge cycles at 0.2 C, the capacity retention rate is still 96.7%.
