Abstract

Nickel-rich-manganese-cobalt oxide (NMC) ternary cathode materials are considered to be one of the most promising cathode materials for lithium-ion batteries due to their high specific capacity and high power. However, most of the current nickel-rich ternary layered materials are polycrystalline particles, and their volumetric energy density and cyclic stability are not satisfactory. Therefore, independent and well-dispersed single-crystal nickel-rich ternary layered materials (SC-NMCs) can be used as the best candidates to replace polycrystalline nickel-rich ternary cathodes. In this paper, we systematically review how to synthesize SC-NMCs and their corresponding relationship with the properties of single-crystal from the perspectives of precursor preparation, material sintering and lithium salt supplementation. Secondly, the performance advantages of SC-NMCs compared with polycrystalline materials are comprehensively summarized, especially the morphology without cracks between particles, which shows good cycling performance. Thirdly, in view of the disadvantages and challenges of the current SC-NMCs, the modification strategies of SC-NMCs, such as element doping, surface modification and double modification, are comprehensively introduced. This review puts forward innovative views on the synthesis and modification of SC-NMCs and provides directional guidance for the application and development of single-crystal nickel-rich ternary layered cathode materials for next-generation lithium-ion batteries.
