“…To stabilize the cathode–electrolyte interface, surface coating of cathode materials by using electrochemically inert species has been widely practiced . Metal oxides and metal phosphates have been tested thoroughly as coating species in light of their extraordinary stability at high voltage as far as both their chemical and electrochemical stability are concerned.…”

As lithium‐ion batteries continue to climb to even higher energy density, they meanwhile cause serious concerns on their stability and reliability during operation. To make sure the electrode materials, particularly cathode materials, are stable upon extended cycles, surface modification becomes indispensable to minimize the undesirable side reaction at the electrolyte–cathode interface, which is known as a critical factor to jeopardizing the electrode performance. This Review is targeted at a precise surface control of cathode materials with focus on the synthetic strategies suitable for a maximized surface protection ensured by a uniform and conformal surface coating. Detailed discussions are taken on the formation mechanism of the designated surface species achieved by either wet‐chemistry routes or instrumental ones, with attention to the optimized electrochemical performance as a result of the surface control, accordingly drawing a clear image to describe the synthesis–structure–performance relationship to facilitate further understanding of functional electrode materials. Finally, perspectives regarding the most promising and/or most urgent developments for the surface control of high‐energy cathode materials are provided.

“…The principle of phosphate-coated positive electrode material is the same as that of oxide coating, in which the phosphate has better ion transportability and thermal stability that can better improve the rate performance of the material. The commonly used phosphates are AlPO 4 [55], Li 3 PO 4 [56,57], Ni 3 (PO 4 ) 2 [58], Co 3 (PO 4 ) 2 [59], and so on.…”

“…The cycle stability of the coated Li Ni 0.815 Co 0.15 Al 0.035 O 2 at room temperature and 55°C can be improved when the coating content reaches 3 wt %, at which point the DSC shows that the heat generation is considerably decreased from 757 J g -1 to 525 J g -1 for NCA and P-NCA. Qi et al [55] successfully improved the electrochemical performance of LiNi 0.8 Co 0.15 Al 0.05 O 2 coated with AlPO 4 composite by the wet coating process. The capacity retention was 86.9% after 150 cycles at 0.5 C, which is significantly higher than the 66.8% of the uncoated sample.…”

Ternary nickel-cobalt lithium aluminate LiNi x Co y Al 1-x-y O 2 (NCA, x ≥ 0:8) is an essential cathode material with many vital advantages, such as lower cost and higher specific capacity compared with lithium cobaltate and lithium iron phosphate materials. However, the noticeably irreversible capacity and reduced cycle performance of NCA cathode materials have restricted their further development. To solve these problems and further improve the electrochemical performance, numerous research studies on material modification have been conducted, achieving promising results in recent years. In this work, the progress of NCA cathode materials is examined from the aspects of surface coating and bulk doping. Furthermore, future research directions for NCA cathode materials are proposed.

“…Because high Ni content exhibits a larger capacity due to the high Li-ion extraction, it results in the increase of exothermic heat and leads to further structural degradation [154,155].Besides NMC, LiNi x Co y Al z O 2 (NCA) are also promising cathode materials due to their high specific energy (see Fig. 1), high specific power, and long lifespan [156,157].

Lithium‐ion batteries are essential mobile power sources for portable devices and energy supplies. Among the various cathode materials, cobalt oxides are the most important materials used in lithium‐ion batteries. But the intrinsic drawbacks of cobalt oxides restrict their wide application. In this paper, we present an overview of current approaches to improve the electrochemical performance of the cathode materials, as well as the capacity and cycling capability of the lithium‐ion batteries.
