摘要

Ni-rich layered oxides have aroused great attentions for the cathode of lithium-ion batteries (LIBs) in recent years due to their low cost and high energy density. However, the intractable issues including structure deterioration, surface side reactions, and low thermal stability of this cathode will lead to fast capacity decay and low rate capability of LIBs. These issues have been investigated and strategies of modifying the cathode materials have been proposed to improve the cycling stability. In this review, we summarize the research advances of the modification strategy on Ni-rich layered oxides, which are combed in terms of surface coating, heteroatom doping, structure engineering of secondary particle, and multiple strategy. Furthermore, prospects of the design and structure engineering of high-performance Ni-rich layered oxide are discussed.
