高镍三元正极材料的失效机理及其改性策略
Failure mechanism and modification strategy of high-nickel ternary cathode materials
摘要
Abstract
In recent years,with the rapid development of the new energy industry,the high-nickel ter-nary cathode materials(NCM/NCA)have become widely used in the lithium battery industry due to their high specific capacity and energy density.Increasing nickel content can enhance the reversible capacity and energy density,but introduce some challenges,such as cation mixing(Li+and Ni2+),lat-tice oxygen release,electrolyte decomposition,and decreased thermal stability.These factors contrib-ute to the performance degradation and safety risks.In order to address these issues,recent research has focused on the surface coating,micro/nanostructure design,and element doping to improve the battery performance and safety by protecting particle surfaces or optimizing crystal structures and particle morphology.These improvement strategies for high nickel cathode materials were summa-rized and compared.关键词
