has been made to explore suitable cathode materials, which are expected to have high capacity, high potential, stable lattice framework, and fast sodium-ion diffusivity. By far, various cathode materials including layered transition-metal oxides, Prussian blue analogues (PBAs), and polyanion-type compounds have been proposed. Although the layered transition-metal oxide materials normally exhibit high theoretical capacity, they suffer from structural instability and unsatisfactory cycle-life. [5][6][7] On the other hand, the applications of PBAs are limited by their low volume density, inferior thermal stability, and toxicity of cyanide. [8][9][10] In this context, great attention has been paid on the polyanion-type materials due to their robust crystal framework with high-level thermal stability, and the moderate capacity with tunable high redox potential, which can achieve high energy density. [11][12][13] Recently, the Na superionic conductor (NASICON)-structured polyanion-type materials are of significant interest because of their unique crystal framework that is constructed by units of MO 6 octahedrons (M represents transition metals) and XO 4 tetrahedrons (X = P, S, Si, As), building 3D ion channels for fast Na + migration. [14][15][16][17][18] Among diverse NASICON-structured compounds, Na 3 V 2 (PO 4 ) 3 is a hotspot, which can deliver a highly reversible capacity over 110 mAh g −1 , and an energy density of over 370 Wh kg −1 as a result of a flat voltage plateau located at 3.3-3.4 V. [19] Although massive work has been reported to promote the development of Na 3 V 2 (PO 4 ) 3 by nanosizing and/or optimizing its poor electronic conductivity, [20][21][22][23] in order to meet the demand of practical applications of Na 3 V 2 (PO 4 ) 3 , improving its operating voltage to reach a higher energy density is urgent. In this regard, researchers have focused on ion-doping strategy to partially substitute V with other elements. Lavela and co-workers used Cr to replace 10% of V and the as-synthesized Na 3 V 1.8 Cr 0.2 (PO 4 ) 3 showed a short plateau above 3.8 V. [24] This high-potential plateau can be prolonged by increasing the amount of Cr to 50%, forming a new material Na 3 VCr(PO 4 ) 3 , which has been reported by Yang and co-workers. [25] In addition, introducing F into Na 3 V 2 (PO 4 ) 3 has been proven effective and the resulting Na 3 V 2 (PO 4 ) 2 F 3 could exhibit an average potential at 3.7-3.8 V, [26][27][28][29] apparently surpassing Na 3 V 2 (PO 4 ) 3 . However, both Cr and F are too expensive and environmentally hazardous to scale-up Na 3 V 2 (PO 4 ) 3 has attracted great attention due to its high energy density and stable structure. However, in order to boost its application, the discharge potential of 3.3-3.4 V (vs Na + /Na) still needs to be improved and substitution of vanadium with other lower cost and earth-abundant active redox elements is imperative. Therefore, the Na superionic conductor (NASICON)structured Na 4 MnV(PO 4 ) 3 seems to be more attractive due to its lower toxicity and higher volt...

“…Besides PO 4 polyanion unit's replacement, metal ion doping, either to sodium or to vanadium, is also demonstrated as an efficient strategy to enhance the efficiency and overall performance of NASICON‐based batteries . For example, the doping of K + to the Na + site in NVP can enhance the rate performance of Na 3 V 2 (PO 4 ) 3 due to the larger atomic size of K + than that of Na + , which can significantly enlarge the lattice volume along the c‐axis and thus increase the Na + diffusion pathway.…”

“…The metal doping to vanadium can affect the electrochemical performance of Na 3 V 2 (PO 4 ) 3 as well. Goodenough et al investigated a class of Na x MV(PO 4 ) 3 (M = Mn, Fe, Ni) obtained through transition metal substitution, and found the NASICON structure could be well maintained after repeated Na + extraction and insertion . Yang et al found that Mg 2+ doping did not change the structure of NVP, but could effectively improve ionic/electronic conductivity and obtain optimized particle size, thus enhancing the rate capability: the specific capacity only decreased from 112.5 to 94.2 mAh g −1 when the current density increased from 1 C to 30 C …”

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.

Aqueous Na-ion batteries may offer a solution to the cost and safety issues of high-energy batteries. However, substantial challenges remain in the development of electrode materials and electrolytes enabling high performance and long cycle life. Herein, we report the characterization of a symmetric Na-ion battery with a NASICON-type Na VTi(PO ) electrode material in conventional aqueous and "water-in-salt" electrolytes. Extremely stable cycling performance for 1000 cycles at a high rate (20 C) is found with the highly concentrated aqueous electrolytes owing to the formation of a resistive but protective interphase between the electrode and electrolyte. These results provide important insight for the development of aqueous Na-ion batteries with stable long-term cycling performance for large-scale energy storage.
