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 f
