富镍三元正极材料的改性研究进展
Research progress on modification of nickel-rich ternary cathode materials
摘要
Abstract
Nickel-rich ternary cathode material is considered as a promising electrode material because of its high energy density and low cost.However,nickel-rich ternary cathode materials also have problems such as capacity attenuation and poor thermal stability.Firstly,the crystal structure characteristics of nickel rich ternary cathode materials are discussed,and the existing problems of ternary cathode materials are briefly summarized.Secondly,the modification methods to improve the electrochemical properties of cathode materials such as morphology control,structure design,doping and coating are reviewed.The effects of fluorine doping and rare-earth element doping,as well as different synthetic methods of coating silica on the electrochemical properties are summarized.Finally,the future development in this field is summarized and prospected.关键词
