“…More relevant reports are expected in the future, however, in regard to this newly found mechanism. [146,147] Similar to NaFePO 4 , NaMnPO 4 also has two types of structure: maricite and olivine. [152] Both structures consist of corner-sharing metal octahedra linked by the oxygen atoms in PO 4 3− groups.…”

Recently, room-temperature stationary sodium-ion batteries (SIBs) have received extensive investigations for large-scale energy storage systems (EESs) and smart grids due to the huge natural abundance and low cost of sodium. The SIBs share a similar "rocking-chair" sodium storage mechanism with lithium-ion batteries; thus, selecting appropriate electrodes with a low cost, satisfactory electrochemical performance, and high reliability is the key point for the development for SIBs. On the other hand, the carefully chosen elements in the electrodes also largely determine the cost of SIBs. Therefore, earth-abundantmetal-based compounds are ideal candidates for reducing the cost of electrodes. Among all the high-abundance and low-cost metal elements, cathodes containing iron and/or manganese are the most representative ones that have attracted numerous studies up till now. Herein, recent advances on both ironand manganese-based cathodes of various types, such as polyanionic, layered oxide, MXene, and spinel, are highlighted. The structure-function property for the iron-and manganese-based compounds is summarized and analyzed in detail. With the participation of iron and manganese in sodium-based cathode materials, real applications of room-temperature SIBs in large-scale EESs will be greatly promoted and accelerated in the near future.

“…For a high-energy-density NIB, it is essential to explore anode materials with high specific capacity delivered at a reasonably low redox potential. Significant reports have been given to developing the high capacity anodes for sodium-ion batteries [11][12][13][14][15]. However, it is difficult for graphite, the widely employed anode material in LIBs, to intercalate sodium ions [8,9].…”

“…In order to unravel the structure evolution of the P2‐NaNMCM electrode upon electrochemical Na + intercalation/deintercalation process, we performed operando XRD experiment and corresponding intensity contour maps are presented in Figure 4 a,b and Figures S20 and S21 (Supporting Information) . No new peaks beyond the P2 structure are detected during the charge process, but only the (002) and (004) diffraction lines of P2‐NaNMCM consecutively shift toward a lower angle.…”

great significance to develop electrochemical energy-storage technique and take advantage of sustainable and renewable energy. [1][2][3][4][5][6][7] Owing to natural abundance, wide availability, and low cost of sodium resources, sodium-ion batteries (SIBs) have been considered as one of most fascinating alternatives to the well-commercialized lithium-ion batteries for future large-scale stationary energy-storage systems with high adaptability and energy efficiency. [8][9][10][11][12][13] To develop satisfactory electrode materials in the future development of SIBs, continued research efforts have been devoted to screen new cathodes over the past few years. [14][15][16][17][18][19] Among a wide variety of cathode candidates including layered oxides, polyanion compounds, and Prussian blue analogues, layered oxide cathode materials have received significant attention because of the high voltage, low cost, and simple synthesis. Recently, research has made dramatic progress especially on manganese-based layered oxides such as zinc-doped Na 0.833 [Li 0.25 Mn 0.75 ]O 2 , Na 0.7 Mg 0.05 [Mn 0.6 Ni 0.2 Mg 0.15 ]O 2 , and Na 2.3 Cu 1.1 Mn 2 O 7−δ , which open new opportunities for developing high-performance cathode materials. [20][21][22][23][24] However, typical P2-type Na 2/3 Ni 1/3 Mn 2/3 O 2 cathode material As one of the most promising cathode candidates for room-temperature sodium-ion batteries (SIBs), P2-type layered oxides face the challenge of simultaneously realizing high-rate performance while achieving long cycle life. Here, a stable Na 2/3 Ni 1/6 Mn 2/3 Cu 1/9 Mg 1/18 O 2 cathode material is proposed that consists of multiple-layer oriented stacking nanoflakes, in which the nickel sites are partially substituted by copper and magnesium, a characteristic of the material that is confirmed by multiscale scanning transmission electron microscopy and electron energy loss spectroscopy techniques. Owing to the optimal morphology structure modulation and chemical element substitution strategy, the electrode displays remarkable rate performance (73% capacity retention at 30C compared to 0.5C) and outstanding cycling stability in Na half-cell system couple with unprecedented full battery performance. The underlying thermal stability, phase stability, and Na + storage mechanisms are clearly elucidated through the systematical characterizations of electrochemical behaviors, in situ X-ray diffraction at different temperatures, and operando X-ray diffraction upon Na + deintercalation/intercalation. Surprisingly, a quasi-solid-solution reaction is switched to an absolute solid-solution reaction and a capacitive Na + storage mechanism is demonstrated via quantitative electrochemical kinetics calculation during charge/discharge process. Such a simple and effective strategy might reveal a new avenue into the rational design of excellent rate capability and long cycle stability cathode materials for practical SIBs.
