“…Cu or Zn doping is used for P2‐Na x (Ni, Mn)O 2 to reduce the occurrence of the P2–O2 transformation at high voltage . In the case of Na 2/3 Ni 1/3 Mn 2/3 O 2 electrode, the Ni 2+ /Ni 3+ /Ni 4+ redox reactions endow it with high specific capacity and high operating voltage.…”

“…The as‐synthesized Cu‐doped P2‐type Na 0.67 N i0.1 Cu 0.2 Mn 0.7 O 2 shows improved battery performance with greatly alleviated structural degradation compared to Na 0.67 Ni 0.3 Mn 0.7 O 2 ( Figure a). The presence of Cu(II) can stabilize the P2 phase, and at the same time contribute to capacity due to the high potential of the Cu 2+ /Cu 3+ redox couple . Similarly, the Zn 2+ doping reduces the degree of distortion of Ni–O octahedra during the charge/discharge processes of Na 0.66 Ni 0.33 Mn 0.66 O 2 while improving the reversibility of the distortion, endowing it with better voltage and capacity retention than Na 0.66 Ni 0.33 Mn 0.66 O 2 (Figure b) .…”

Sodium‐ion batteries (SIBs) are attracting increasing attention and considered to be a low‐cost complement or an alternative to lithium‐ion batteries (LIBs), especially for large‐scale energy storage. Their application, however, is limited because of the lack of suitable host materials to reversibly intercalate Na+ ions. Layered transition metal oxides (NaxMO2, M = Fe, Mn, Ni, Co, Cr, Ti, V, and their combinations) appear to be promising cathode candidates for SIBs due to their simple structure, ease of synthesis, high operating potential, and feasibility for commercial production. In the present work, the structural evolution, electrochemical performance, and recent progress of NaxMO2 as cathode materials for SIBs are reviewed and summarized. Moreover, the existing drawbacks are discussed and several strategies are proposed to help alleviate these issues. In addition, the exploration of full cells based on NaxMO2 cathodes and future perspectives are discussed to provide guidance for the future commercialization of such systems.

“…The existence of Cu can not only stabilize the crystal structure against the detrimental phase transition, thus suppress the severe voltage and capacity decay, but also offer high potential due to the high Cu 2+ /Cu 3+ redox. Consequently, the formulated P2‐type Na 0.67 Ni 0.1 Cu 0.2 Mn 0.7 O 2 showed much‐alleviated structural degradation and favorable battery performance with a moderate rate capability . This strategy paved new ways to prepare high power materials.…”

The increasing demands for renewable energy to substitute traditional fossil fuels and related large‐scale energy storage systems (EES) drive developments in battery technology and applications today. The lithium‐ion battery (LIB), the trendsetter of rechargeable batteries, has dominated the market for portable electronics and electric vehicles and is seeking a participant opportunity in the grid‐scale battery market. However, there has been a growing concern regarding the cost and resource availability of lithium. The sodium‐ion battery (SIB) is regarded as an ideal battery choice for grid‐scale EES owing to its similar electrochemistry to the LIB and the crust abundance of Na resources. Because of the participation in frequency regulation, high pulse‐power capability is essential for the implanted SIBs in EES. Herein, a comprehensive overview of the recent advances in the exploration of high‐power cathode and anode materials for SIB is presented, and deep understanding of the inherent host structure, sodium storage mechanism, Na+ diffusion kinetics, together with promising strategies to promote the rate performance is provided. This work may shed light on the classification and screening of alternative high rate electrode materials and provide guidance for the design and application of high power SIBs in the future.

“…As one of effective energy devices, lithium-ion batteries (LIBs) have been widely used in portable electronics, and are being applied in electric vehicles (EVs) and hybrid electric vehicles (HEVs), owing to their excellent characteristics of high-energy density and long cycling life [1][2][3]. More recently, sodium-ion batteries (SIBs) have also attracted great attention as potential energy storage applications because of the low cost, abundant reserves and better safety of sodium [4][5][6]. However, they are facing the same challenge in exploring high-capacity anode materials for both LIBs and SIBs.…”

MoO 2 @N-doped C nanofibers (MoO 2 @NC NFs) were synthesized by electrospinning with polyacrylonitrile as carbon source. The in situ formed MoO 2 nanocrystals are completely embedded in the carbon nanofibers, which can not only accelerate ion transition, but also act as a buffer to avoid the mechanical degradation of active material due to the volume changes during charge/discharge cycling. When used as the anode material for both Li/Na-ion batteries, the as-synthesized MoO 2 @NC NFs displayed excellent Li + /Na + storage properties. As the anode for Li-ion battery, the MoO 2 @NC NFs display a high discharge capacity of 930 mA h g −1 at a current density of 200 mA g −1 for 100 cycles, and 720 mA h g −1 at a current density of 1 A g −1 for 600 cycles. Moreover, the discharge capacity of 350 mA h g −1 could be realized at a current density of 100 mA g −1 for 200 cycles for Na-ion battery.
