高镍系三元层状氧化物正极材料容量衰减机理的研究进展
Research Progress on the Capacity Fading Mechanisms of High-Nickel Ternary Layered Oxide Cathode Materials
摘要
Abstract
Owing to advantages of high specific capacity,low cost and environmental friendliness,high-nickel ternary layered oxide cathode materials have received much attention and have been extensively studied over the past ten years.However,its further application is hindered by its structural instability during the cycling,thermal instability and poor storage properties.In order to provide references to tackle the problems that high nickel ternary layered oxide cathode materials faces,the degradation mechanisms of high-nickel ternary layered oxide cathode materials during cycling was summarized and discussed in this review.The degradation mechanisms are categorized as two major factors.One is thermodynamic factors including cation disorder as well as surface reactions,and the other is kinetic factors comprising of micro-cracks formation as well as rearrangement of conductive materials.The modification strategies corresponding to the major mechanisms and the research focusing on initial irreversible capacity loss are also briefly introduced.关键词
