“…[ 129 ] Early studies introduced NASICON-type compounds as Na-ion conducting solid electrolytes (e.g., Na 1+x ZrP 3-x Si x O 12 ); [ 125 ] however, more recently, various V-based intercalation compounds were reported as high-energy cathodes based on the multi-electron redox reaction of V 2+ /V 3+ , V 3+ /V 4+ , and V 4+ /V 5+ . [ 106,[126][127][128] Tremendous efforts have been focused on improving the electrochemical properties of Na 3 V 2 (PO 4 ) 3 electrodes since the Na de/ intercalation behavior of a Na 3 V 2 (PO 4 ) 3 electrode was reported by Uebou et al [ 130 ] Approximately two Na ions (117 mA h g −1 ) can be extracted and reinserted into the electrode at ≈3.6 V with a redox reaction of V 3+ /V 4+ , and the biphasic reaction between Na 3 V 2 (PO 4 ) 3 and NaV 2 (PO 4 ) 3 with a small volume change of 8.26% was confi rmed by Jian et al [ 127,130 ] The electrochemical activity was also observed in the low-voltage region at approximately 1.6 V with a redox reaction of V 2+ /V 3+ .…”

“…The Na de/intercalation behavior in (MoO 2 ) 2 P 2 O 7 was examined by Uebou et al [ 221 ] They revealed that approximately 3.1 Na, which corresponds to a capacity of 190 mA h g −1 , can intercalate into the structure with a concurrent crystalline-to-amorphous phase transformation. Amorphous NaFe 3 (SO 4 ) 2 (OH) 6 was also examined as a Na intercalation host.…”

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.

“…Ion-exchanged Li 3 Fe 2 (PO 4 ) 3 from Na 3 Fe 2 (PO 4 ) 3 is known to be electrochemically active in Li cells [39]. Approximately 0.4 mole of Na is reversibly inserted/extracted into/from Na 3 Fe 2 (PO 4 ) 3 in Na cells [136], even though ionic conductivity of Na 3 Fe 2 (PO 4 ) 3 is reported to be very low (1.2 × 10 −7 S cm −1 at 50 °C) [137]. …”

Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxides, phosphates, fluorides, etc, as positive electrodes for rechargeable sodium batteries are reviewed. Iron and manganese compounds with sodium ions provide high structural flexibility. Two layered polymorphs, O3- and P2-type layered structures, show different electrode performance in Na cells related to the different phase transition and sodium migration processes on sodium extraction/insertion. Similar to layered oxides, iron/manganese phosphates and pyrophosphates also provide the different framework structures, which are used as sodium insertion host materials. Electrode performance and reaction mechanisms of the iron- and manganese-based electrode materials in Na cells are described and the similarities and differences with lithium counterparts are also discussed. Together with these results, the possibility of the high-energy battery system with electrode materials made from only Earth-abundant elements is reviewed.

“…Meanwhile Na-ion battery has drawn our attention as low cost and low environmental impact power device in recent years, because of the good economical efficiency, rich resources and low toxic nature [10][11][12][13][14]. However, the standard electrode potential of Na (−2.71 V vs. SHE) is not low as that of Li (−3.05 V vs. SHE).…”
