“…With this in mind, preventing the direct contact between the NCA material with the electrolyte by surface coating is an effect strategy [20][21][22] . Generally, an ideal surface coating layer should possess properties as follows: good structural stability, excellent chemical stability against both NCA and electrolyte, high ionic conductivity for fast Li + transport, and the same or close to the bulk phase element, such as Al 2 O 3 [23] , Li 4 Ti 5 O 12 [24] , SiO 2 [25] , AlF 3 [26] , Li 3 PO 4 [27] , Ni 3 (PO 4 ) 2 [28] , FePO 4 [29] . Recent, Sun et al have shown that it is effective to use a solid electrolyte to rearrange the grain boundary of a high nickel positive electrode can provide a fast path for the Li + transport and simultaneously prevents penetration of the liquid electrolyte into the boundary [30] .…”

“…This electrode delivered a capacity of 153.7 mAh g −1 at 5 C, and 107.5 mAh g −1 after 300 cycles at 5 C, corresponding to a retention of 90%. NCA was also coated with FePO 4 by Huang et al [107], and more recently by Xia et al who used a liquid phase process [108]. At 1 C rate, the capacity was 160 mAh g −1 , with a capacity retention of 85.82% for the optimized amount 2 wt.% FePO 4 .…”

The aim of this article is to examine the progress achieved in the recent years on two advanced cathode materials for EV Li-ion batteries, namely Ni-rich layered oxides LiNi0.8Co0.15Al0.05O2 (NCA) and LiNi0.8Co0.1Mn0.1O2 (NCM811). Both materials have the common layered (two-dimensional) crystal network isostructural with LiCoO2. The performance of these electrode materials are examined, the mitigation of their drawbacks (i.e., antisite defects, microcracks, surface side reactions) are discussed, together with the prospect on a next generation of Li-ion batteries with Co-free Ni-rich Li-ion batteries.

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.
