“…Through this modulation, p‐NVFP obtains the preferable buffer ability of Na + , whose volume change is significantly lower than other NASICON materials in Figure 4d . [ 4 , 9 , 21 ] In summary, the “pearl” structure makes the Fe 2+ of NVFP take surface oxidation, assisting more deintercalation of Na + along c axis in the initial structural adjustment and stimulating the subsequent V 3+ /V 4+ redox completely.…”

Based on the favorable ionic conductivity and structural stability, sodium superionic conductor (NASICON) materials especially utilizing multivalent redox reaction of vanadium are one of the most promising cathodes in sodium‐ion batteries (SIBs). To further boost their application in large‐scale energy storage production, a rational strategy is to tailor vanadium with earth‐abundant and cheap elements (such as Fe, Mn), reducing the cost and toxicity of vanadium‐based NASICON materials. Here, the Na3.05V1.03Fe0.97(PO4)3 (NVFP) is synthesized with highly conductive Ketjen Black (KB) by ball‐milling assisted sol‐gel method. The pearl‐like KB branch chains encircle the NVFP (p‐NVFP), the segregated particles possess promoted overall conductivity, balanced charge, and modulated crystal structure during electrochemical progress. The p‐NVFP obtains significantly enhanced ion diffusion ability and low volume change (2.99%). Meanwhile, it delivers a durable cycling performance (87.7% capacity retention over 5000 cycles at 5 C) in half cells. Surprisingly, the full cells of p‐NVFP reveal a remarkable capability of 84.9 mAh g−1 at 20 C with good cycling performance (capacity decay rate is 0.016% per cycle at 2 C). The structure modulation of the p‐NVFP provides a rational design on the superiority of others to be put into practice.

Sodium‐ion batteries (SIBs) are promising in several aspects due to their many advantages over lithium‐ion batteries. Among SIB’s several outstanding attributes, its low cost, resource abundance, and potential safety make it suitable for large‐scale energy storage systems (ESS). Among the potential cathode materials, poly‐anionic cathode materials could be a better choice for their stability and safety in comparison to layered transition metal oxides and Prussian blue analogues (PBA). However, on the other hand, the conductivity as well as the available capacity of the polyanion compounds are still poor, which limits their applications; moreover, some polyanion cathode operate at low voltage, which reduces the energy density and raises the cost of the battery system. We here try to summarize the recent progress of polyanion compounds as cathode materials for SIB. These compounds are categorized based on the metal redox couple, including V‐, Cr‐, Mn‐, Fe‐, Co‐, and Ni‐polyanion compounds. Our attention is specifically drawn to properties such as reversible redox voltage, capacity, cycling stability, and sodium storage mechanisms. We also discuss the challenges and potential development strategies for the future.

The extraction of vanadium from spent industrial catalysts is a widely practiced process globally due to the large quantities of material available with appreciable vanadium content. However, some of these spent catalysts are unresponsive to established extraction methods because they have different properties. Therefore, separate studies are necessary to deal with specific cases. This work demonstrates how the leaching step can limit the recovery of vanadium to the solution before the coprecipitation step. The NH4Cl‐H2SO4 synergetic system achieved a high vanadium leaching rate of up to 95 %, resulting in the preparation of high‐purity NH4VO3 with 75.45 % V2O5 content. This demonstrates the potential of the prepared V2O5 as a precursor for vanadium materials used in sodium‐ion batteries, allowing for the adjustment of the valence of vanadium. The Na3V2(PO4)3@C particles exhibit a discharge capacity of 110 mAh g−1 at a current density of 0.1 C and 90 mAh g−1 at 1 C. The synergistic leaching system provides a sustainable method for the recovery and reuse of vanadium from spent vanadium catalysts. This contributes to recycling efforts and the development of sodium‐ion batteries.
