“…As an example (the electrode nature), a narrow beginning arch for LFP indicates that the intermediate phase region should be thin for this cathode material, in contrast to other cathodes, e.g. LiFeSO 4 F, 45,74 Na 2 FePO 4 F, 77,79 etc. If a parameter ( e.g.…”

“…Unfortunately, the Mn doping seems to be adverse for the increase in energy density due to the significant capacity loss, because incorporation of Mn into the materials would induce a structure transformation from the layered to tunnel phase, leading to the deactivation of Fe/Mn elements. Recently, Cai et al proposed a porous carbon coating strategy to enhance the electrochemical performance of the Na 2 FePO 4 F (Figure H) . Thanks to the reduced particle size and appropriate carbon coating, the optimal samples demonstrate enhanced kinetics and rate capability, but the cycling stability needs further improvement.…”

Na-ion batteries (NIBs) as a supplement to Li-ion batteries deliver huge application potential in the field of grid-scale energy storage. At present, it is a particularly imperative to advance commercialization of the NIBs after ten years of intensive research. Among the exploited cathodes for NIBs, polyanionic compounds have great commercial prospects due to their favorable ion diffusion channels, high safety, and superior structure stability determined by their unique structure framework; however, there is still a long way to go before large-scale industrialization can be realized. This outlook summarizes the recent progress of polyanion-type cathodes for NIBs and includes V-based, Fe-based, and Mn-based polyanionic compounds toward high energy density and long cycle lifespan. The remaining challenges and guidelines/suggestions for the design of the practically available polyanionic cathode materials with desirable energy density and cycling performance are presented. We hope that this outlook can provide some insights into the development of polyanionic cathodes for practical NIBs toward commercialization.

“…They found that the electrode with a molar ratio of 4:1 exhibited a better rate performance and longer cycle life (Figure 11h). [202] Mahmoud et al successfully prepared the Na 2 FePO 4 F-C composite powder by adding 10% and 20% carbon black (CB) or CNTs. The result showed that carbon nanotubes are a better alternative for increasing the capacity of NFPF electrode materials owing to superior dispersion effects.…”

The development of large‐scale energy storage systems (EESs) is pivotal for applying intermittent renewable energy sources such as solar energy and wind energy. Lithium‐ion batteries with LiFePO4 cathode have been explored in the integrated wind and solar power EESs, due to their long cycle life, safety, and low cost of Fe. Considering the penurious reserve and regional distribution of lithium resources, the Fe‐based sodium‐ion battery cathodes with earth‐abundant elements, environmental friendliness, and safety appear to be the better substitutes in impending grid‐scale energy storage. Compared to the transition metal oxide and Prussian blue analogs, the Fe‐based polyanionic oxide cathodes possess high thermal stability, ultra‐long cycle life, and adjustable voltage, which is more commercially viable in the future. This review summarizes the research progress of single Fe‐based polyanionic and mixed polyanionic oxide cathodes for the potential sodium‐ion batteries EESs candidates. In detail, the synthesized method, crystal structure, electrochemical properties, bottlenecks, and optimization method of Fe‐based polyanionic oxide cathodes are discussed systematically. The insights presented in this review may serve as a guideline for designing and optimizing Fe‐based polyanionic oxide cathodes for coming commercial sodium‐ion batteries EESs.
