Although layered Ni‐rich cathode materials have attracted lots of attention for their high capacity and power density, several significant issues, such as poor thermal stability and moderate cyclability, limit their practical applications. Most of these undesired problems of Ni‐rich materials are caused by the unstable surface or the parasitic reactions at cathode‐electrolyte interface. Surface coating is the most common method to suppress such interfacial problems for Ni‐rich materials. This review focuses on the surface engineering of the Ni‐rich materials in recent years, including the species used in coating, synthetic strategies of uniform coating layer, and the positive effects of coating species on the active materials. Detailed discussions are also taken to describe the formation mechanism of the surface coating layer with design philosophy. Finally, the prospects for further developments and challenges in surface coating are also summarized.

锂离子电池用富镍材料表面改性的研究进展和前景†

尽管层状富镍阴极材料因其高容量和高功率密度而备受关注，但一些重要问题（例如差的热稳定性和适度的可循环性）限制了它们的实际应用。这些富镍材料的不希望有的大多数问题是由表面不稳定或阴极-电解质界面处的寄生反应引起的。表面涂层是抑制此类富镍材料界面问题的最常用方法。这篇综述着重于近年来的富镍材料的表面工程，包括用于涂层的物种，均匀涂层的合成策略以及涂层物种对活性材料的积极影响。还采用设计思想对表面涂层的形成机理进行了详细讨论。最后，还总结了表面涂层的进一步发展和挑战的前景。
