“…Advance in cathode materials is of great importance in accelerating the commercialization of SIBs due to their relatively low capacity value [4,5] and poor rate capability [5,6] compared with the anode counterparts [7][8][9]. Nickel hexacyanoferrate (NiHCF), a compound with [10], the PB analogues have attracted growing interests owing to the advantages of the rigid open framework for Na-ion diffusion, the tunable composition, the non-toxicity and the low cost [11][12][13][14][15][16][17]. Therein, iron hexacyanferrate (FeHCF) is under most investigation due to its two-electron-redox processes and the corresponding high theoretical capacity of ~170 mAh g -1 (based on Na 2 FeFe(CN) 6 ) [13,[18][19][20].…”

“…[ 238 ] The family of alkali-ion-defi cient cubic AM II Fe III (CN) 6 (A = Na or K) compounds requires a presodiation process to be combined with conventional Na-free anodes; otherwise, the electrode operation undergoes only one electron transfer with Fe 3+ /Fe 2+ redox couples, resulting in a low capacity below 70 mA h g −1 . [239][240][241][242][243] The Na-rich compound, Na 1.72 MnFe(CN) 6 , was successfully synthesized by Wang et al [ 229 ] This electrode delivers a capacity of 130 mA h g −1 with a high average voltage of 3.4 V involving Mn 2+ /Mn 3+ and Fe 2+ /Fe 3+ redox reactions. The high Na concentration in the structure induces a structural transition from cubic to rhombohedral symmetry with cooperative Na displacement along the [ 111 ] direction.…”

Grid‐scale energy storage systems (ESSs) that can connect to sustainable energy resources have received great attention in an effort to satisfy ever‐growing energy demands. Although recent advances in Li‐ion battery (LIB) technology have increased the energy density to a level applicable to grid‐scale ESSs, the high cost of Li and transition metals have led to a search for lower‐cost battery system alternatives. Based on the abundance and accessibility of Na and its similar electrochemistry to the well‐established LIB technology, Na‐ion batteries (NIBs) have attracted significant attention as an ideal candidate for grid‐scale ESSs. Since research on NIB chemistry resurged in 2010, various positive and negative electrode materials have been synthesized and evaluated for NIBs. Nonetheless, studies on NIB chemistry are still in their infancy compared with LIB technology, and further improvements are required in terms of energy, power density, and electrochemical stability for commercialization. Most recent progress on electrode materials for NIBs, including the discovery of new electrode materials and their Na storage mechanisms, is briefly reviewed. In addition, efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials are discussed.

Grid-scale energy storage systems with low-cost and high-performance electrodes are needed to meet the requirements of sustainable energy systems. Due to the wide abundance and low cost of sodium resources and their similar electrochemistry to the established lithium-ion batteries, sodium-ion batteries (SIBs) have attracted considerable interest as ideal candidates for grid-scale energy storage systems. In the past decade, though tremendous efforts have been made to promote the development of SIBs, and significant advances have been achieved, further improvements are still required in terms of energy/ power density and long cyclic stability for commercialization. In this review, the latest progress in electrode materials for SIBs, including a variety of promising cathodes and anodes, is briefly summarized. Besides, the sodium storage mechanisms, endeavors on electrochemical property enhancements, structural and compositional optimizations, challenges and perspectives of the electrode materials for SIBs are discussed. Though enormous challenges may lie ahead, we believe that through intensive research efforts, sodium-ion batteries with low operation cost and longevity will be commercialized for large-scale energy storage application in the near future.
