“…The intensity of the component at 73.3 eV is far lower than that at 74.1 eV, which could be tentatively assigned to Li 5 AlO 4 and LiAlO 2 , respectively. [29] The percentages of the components at 73.3 and 74.1 eV are close to those obtained by XRD, as shown in Table 1. Figure 6 shows the initial charge/discharge curves of all samples at 0.1 C, the charge/discharge curves at 10 C, rate capability and cycling performances at 1 C. It can be clearly seen that all samples have the similar initial charge/ discharge curves with different discharge capacities at 0.1 C. With the increased lithium aluminates the discharge capacity decreases, such as 199.…”

Ni‐rich layered compounds are very promising cathodes for lithium ion batteries whose surface modifications are normally required. As excellent lithium‐conducting solid electrolytes lithium aluminates such as LiAlO2 are expected to have an important role to play as a candidate for surface modifications. Here, Ni‐rich layered LiNi0.8Co0.1Mn0.1O2 (NCM) coated by lithium aluminates with different nominal weight percentages was prepared using a sol‐gel method. Lithium aluminates are found to be a mixture of major LiAlO2 and minor Li5AlO4. The coatings almost have no influence on the size and morphology of NCM particles, and however favor the order degree of structure and change the surface states. The electrical conductivity and charge transfer resistance can be optimized by controlling the amount of lithium aluminates. The cycling stability at low rates such as 1 C tends to increase with the amount of lithium aluminates whereas the rate capability can be achieved at certain amount, which is probably related to the enhancement of electrical conductivity and the improved surface protection against the erosion by electrolyte. This study reveals that the performances of NCM can be significantly improved and tailored by controlling the amount of lithium aluminates.

Driven by the increasing plea for greener transportation and efficient integration of renewable energy sources, Ni-rich metal layered oxides, namely NMC, Li [Ni1−x−yCoyMnz] O2 (x + y ≤ 0.4), and NCA, Li [Ni1−x−yCoxAly] O2, cathode materials have garnered huge attention for the development of Next-Generation lithium-ion batteries (LIBs). The impetus behind such huge celebrity includes their higher capacity and cost effectiveness when compared to the-state-of-the-art LiCoO2 (LCO) and other low Ni content NMC versions. However, despite all the beneficial attributes, the large-scale deployment of Ni-rich NMC based LIBs poses a technical challenge due to less stability of the cathode/electrolyte interphase (CEI) and diverse degradation processes that are associated with electrolyte decomposition, transition metal cation dissolution, cation–mixing, oxygen release reaction etc. Here, the potential degradation routes, recent efforts and enabling strategies for mitigating the core challenges of Ni-rich NMC cathode materials are presented and assessed. In the end, the review shed light on the perspectives for the future research directions of Ni-rich cathode materials.

“…LiF, Li 2 CO 3 , LiOH, and other impurities are easily deposited on the interface between the active high nickel LNCM positive electrode and the electrolyte, thereby suppressing the diffusion of Li + and reducing the electrochemical performance. To effectively prevent the side reaction between the electrode and the electrolyte, coating modification is proposed, such as coating metal oxides: Al 2 O 3 (Liao and Manthiram, 2015;Yan et al, 2016), ZrO 2 (Yang et al, 2019a), MgO (Yoon et al, 2012), ZnO (Chang et al, 2010), lanthanide oxides: La 4 NiLiO 8 , phosphate: AlPO 4 (Zhao et al, 2017), Cu 3 (PO 4 ) 2 (Zhao et al, 2016), fluoride: AlF 3 (Ding et al, 2017), transition metal oxide: Li 2 ZrO 3 (Xu et al, 2016), multiple coating: Li 2 TiO _ 3 Li 2 ZrO 3 , and LiFePO _ 4 Al 2 O 3 (Seteni et al, 2017). The double modification method combines doping and coating, as follows: Sr doping-LaMnO 3 coating , N doping-C coating (Nanthagopal et al, 2019), Zr doping-ZrO 2 coating (Wang et al, 2020e), and Sn doping-Li 2 SnO 3 coating (Zhu et al, 2020).…”

To address increasingly prominent energy problems, lithium-ion batteries have been widely developed. The high-nickel type nickel-cobalt-manganese (NCM) ternary cathode material has attracted attention because of its high energy density, but it has problems such as cation mixing. To address these issues, it is necessary to start from the surface and interface of the cathode material, explore the mechanism underlying the material's structural change and the occurrence of side reactions, and propose corresponding optimization schemes. This article reviews the defects caused by cation mixing and energy bands in high-nickel NCM ternary cathode materials. This review discusses the reasons why the core-shell structure has become an optimized high-nickel ternary cathode material in recent years and the research progress of core-shell materials. The synthesis method of high-nickel NCM ternary cathode material is summarized. A good theoretical basis for future experimental exploration is provided.
