“…doping on NCA, which demonstrated excellent cycling performance especially at high voltage and elevated temperature. [110] More recently, Li et al reported that doping halogen in Ni-rich cathodes could induce favorable cation antisite formation, and hence significantly improve the electrochemical and thermal stability. [111] First-principles calculation revealed that the halogen substitution could facilitate the exchange of the adjacent Li + and Ni 2+ to from a lower total energy and more stable local octahedron structure, which is due to the stronger bond strength of X-Li than X-Ni.…”

Nickel-rich layered lithium transition metal oxides (LiNi 1−x−y Co x Mn y O 2 and LiNi 1−x−y Co x Al y O 2 , x + y ≤ 0.2) are the most attractive cathode materials for the next generation lithium-ion batteries for automotive application. However, they suffer from structural/interfacial instability during repeated charge/discharge, resulting in severe performance degradation and serious safety concerns. This work provides a comprehensive review about challenges and strategies to advance nickel-rich layered cathodes specifically for harsh (high-voltage, hightemperature, and fast charging) operations. Firstly, the degradation pathways of nickel-rich cathodes including surface/interface degradation, undesired cathode-electrolytes parasitic reactions, gas evolution, inter/intragranular cracking, and electrical/ionic isolation are discussed. Then, recent achievements in stabilizing the structure/interface of nickel-rich cathodes via surface coating, cation/anion doping, composition tailoring, morphology engineering, and electrolytes optimization are summarized. Moreover, challenges and strategies to improve the performance of Ni-rich cathodes at the electrode level are discussed. Outlook and perspectives to promote the practical application of nickel-rich layered cathodes toward automotive application are provided as well.

“…Doping has been widely demonstrated to be the simplest approach for enhancing the structural and thermal stabilities of the Ni-rich cathodes. Typically, to date, a wide range of dopants including cations doping (Mg, [211,242] Al, [67,129,140,[243][244][245][246] Ti, [209,211] Zr, [208,[247][248][249] Nb, [250] Cd, [251] Ce, [252] Mo, [87] Ca, [253] Ta, [211] V, [254] Na [255,256] W, [257,258] and B, [132,259] ) and anions doping (F, [260,261] Cl, [262] and S, [263] ) have been introduced into the Ni-rich cathodes. The origins for the obviously improved structural stabilities by doping are closely associated with the three aspects as follows: i) the reinforcement of the bonding energy between TM ions and oxygen, ii) the suppression of the detrimental phase distortion from the layered to rocksalt structure, and iii) the promotion of the Li-ion migration thanks to increased Li slab distance by the dopants.…”

Nickel‐rich layered transition‐metal oxides with high‐capacity and high‐power capabilities are established as the principal cathode candidates for next‐generation lithium‐ion batteries. However, several intractable issues such as the poor thermal stability and rapid capacity fade as well as the air‐sensitivity particularly for the Ni content over 80% have seriously restricted their broadly practical applications. The properties and nature of the stable surface/interface, where the Li+ shuttles back and forth between the cathode and electrolyte, play a significant role in their ultimate lithium‐storage performance and industrial processability. Thus, tremendous efforts are made to in‐depth understanding of the essential origins of surface/interface structure degradation and efficient surface modification methodologies are intensively explored. The purpose of the contribution is first to provide a comprehensive review of the up‐to‐date mechanisms proposed to rationally elucidate the surface/interface behaviors, and then, focus on recent developed strategies to optimize the surface/interface structure and chemistry including synthetic condition regulation, surface doping, surface coating, dual doping‐coating modification, and concentration‐gradient structure as well as electrolyte additives. Finally, the perspective on future research trends and feasible approaches toward advanced Ni‐rich cathodes with stable surface/interface is presented briefly.

“…As an oxide in the same main group as aluminum, many studies have focused on B 2 O 3 for its strong B−O bond (B−O bond enthalpy: 809 kJ mol −1 ) and stability . It has been confirmed that the addition of B 2 O 3 or H 3 BO 3 during a lithiation process for a hydroxide precursor can significantly increase the cyclic stability of LiNi 0.8 Co 0.15 Al 0.05 O 2 and Li[Ni 0.90 Co 0.05 Mn 0.05 ]O 2 owing to the doping of B 3+ . Previously, Zhou et al proved that a LiCoO 2 electrode coated with B 2 O 3 had better performance at high voltage.…”

Ni‐rich cathode is considered a promising cathode for its high specific capacity. However, a sharp capacity attenuation induced by interface problems limits the application of the cathode material. Herein, we propose a practical surface modification strategy by introducing diboron trioxide (B2O3) to the surface of LiNi0.83Co0.12Mn0.05O2 (NCM) cathode materials. B2O3‐modified NCM shows superior cyclic stability with a capacity retention of 87.7 % at 1 C after 200 cycles in comparison to 69.4 % for a bare NCM. On the basis of material and electrochemical characterizations, we conclude that the superior cycle stability of B2O3‐modified NCM material benefits from the formation of B2O3 coating and B3+ doping on the surface. The B2O3 coating layer that is confirmed by scanning and transmission electron microscopy can suppress surface side reactions and reduce the content of Li2CO3 on the surface. The B3+‐doping surface is verified by X‐ray diffraction and X‐ray photoelectron spectroscopy and triggers a reduction of a small amount of Ni3+ to Ni2+. Furthermore, the combination of surface B2O3 coating and B3+ doping inhibits the irreversible phase transitions and extension of microcracks in the NCM material. The above surface modification strategy provides a direction for the acquisition of long‐life cathode materials.
