“…However, most of them suffer from structural instability during Na‐insertion/extraction reactions. For example, the Na ion insertion/extraction in the layered metal oxides often results in very complicated multiphase transitions, leading to rapid structural degradation of the hosts during cycling 7. In addition, they are very sensitive to atmosphere and water, making the large scale application of these materials a severe problem 5.…”

Sodium ion batteries (SIBs) have been considered as a promising alternative for the next generation of electric storage systems due to their similar electrochemistry to Li‐ion batteries and the low cost of sodium resources. Exploring appropriate electrode materials with decent electrochemical performance is the key issue for development of sodium ion batteries. Due to the high structural stability, facile reaction mechanism and rich structural diversity, phosphate framework materials have attracted increasing attention as promising electrode materials for sodium ion batteries. Herein, we review the latest advances and progresses in the exploration of phosphate framework materials especially related to single‐phosphates, pyrophosphates and mixed‐phosphates. We provide the detailed and comprehensive understanding of structure–composition–performance relationship of materials and try to show the advantages and disadvantages of the materials for use in SIBs. In addition, some new perspectives about phosphate framework materials for SIBs are also discussed. Phosphate framework materials will be a competitive and attractive choice for use as electrodes in the next‐generation of energy storage devices.

“…Similar to their Li counterparts,1 though sodium‐based system has similar electrochemical reaction characteristics compared to lithium‐based one, the larger ionic radius for sodium ion cause sluggish kinetics and volume change during Na storage, leading to lower capacity, poor cycling and rate properties of the Na storage materials. Recently, major efforts have been devoted to promote the electrochemical performance of Na storage materials, for example, Na x MO 2 ,2, 3, 4, 5, 6, 7, 8, 9, 10 polyanionic framework compounds,11, 12, 13, 14, 15, 16, 17, 18, 19 hexacyanoferrate,20, 21, 22, 23, 24, 25, 26, 27 for the cathode materials, and hard carbons,28, 29, 30, 31, 32, 33 alloys,34, 35, 36, 37, 38, 39, 40, 41 oxides,42, 43 sulfides37, 44, 45, 46 for the anode materials.…”

Sodium‐ion batteries are now considered as a low‐cost alternative to lithium‐ion technologies for large‐scale energy storage applications; however, their safety is still a matter of great concern for practical applications. In this paper, a safer sodium‐ion battery is proposed by introducing a nonflammable phosphate electrolyte (trimethyl phosphate, TMP) coupled with NaNi0.35Mn0.35Fe0.3O2 cathode and Sb‐based alloy anode. The physical and electrochemical compatibilities of the TMP electrolyte are investigated by igniting, ionic conductivity, cyclic voltammetry, and charge–discharge measurements. The results exhibit that the TMP electrolyte with FEC additive is completely nonflammable and has wide electrochemical window (0–4.5 V vs. Na/Na+), in which both the Sb‐based anode and NaNi0.35Mn0.35Fe0.3O2 cathode show high reversible capacity and cycling stability, similarly as in carbonate electrolyte. Based on these results, a nonflammable sodium‐ion battery is constructed by use of Sb anode, NaNi0.35Mn0.35Fe0.3O2 cathode, and TMP + 10 vol% FEC electrolyte, which works very well with considerable capacity and cyclability, demonstrating a promising prospect to build safer sodium‐ion batteries for large‐scale energy storage applications.

“…The average discharge voltage is ∼3.16 V vs. Na + /Na. Na 3 Ni 2 SbO 6 has been shown to exhibit a superior rate capability by Yang et al 9 At 10C rate, the capacity reached 104 mAh/g, which exceeds 85% of its capacity at C/10 (117 mAh/g). Unfortunately, the rate capability for Na 3 Ni 2 BiO 6 is less attractive.…”

“…Yang et al attributed the superior rate capability of Na 3 Ni 2 SbO 6 to the weaker attraction force between sodium and the structure. 9 The average bond length of Na-O in Na 3 Ni 2 SbO 6 is 2.434 Å, larger than that in Na 3 Ni 2 BiO 6 (2.395 Å).…”

Honeycomb compound Na 3 Ni 2 BiO 6 was synthesized and studied as positive electrode material in sodium cells for the first time. This material exhibits a reversible capacity of ∼80 mAh/g and an average voltage of ∼3.1 V, corresponding to the reversible removal of half of the sodium from the structure. The sodiation/desodiation mechanism was studied by in situ X-ray diffraction and involves multiple phase transitions. It was observed that the phase transitions are different for the first charge/discharge processes, possibly due to kinetic hindrance. The multiple phase transitions may lead to sluggish kinetics that are responsible for the poor rate capability. © The Author ( Sodium ion batteries have attracted much attention in the past few years for their potential application in large scale grid storage.1 Compared to lithium, sodium is more abundant and uniformly distributed on earth. The basic chemistry of sodium ion batteries is similar to that of lithium ion batteries, excepting that the active ion is sodium. The battery performance depends on the combined effects of the positive electrode, negative electrode, and electrolyte. Positive electrode material development is of importance to the commercialization of sodium ion batteries. Among many candidates for positive electrode materials, most research has been focused on layered sodium transition metal oxides.2 These materials generally show good electrochemical performance and structural stability.2 Nickel-based materials have been extensively studied as they offer high voltage and high capacity.
