“…In the FESEM images of both NVP/C–Na and NVP materials, nanospherical particles of different sizes are evident in all samples. As depicted in Figure b–d, the NVP/C–Na materials exhibit microspheres with a uniformly coated surface of carbon layer containing nanoparticles, these particles are expected to boost the electrochemical characteristics of the electrodes of Na 3 V 2 (PO 4 ) 3 . , Additionally, the materials possess a porous structure that typically arises from vigorous gas precipitation (such as H 2 O, CO, CO 2 , etc.) during oxalic acid and Na 2 CO 3 decomposition.…”

Sodium-ion batteries are recognized as a more costeffective choice for large-scale energy system storage compared to lithium-ion batteries. Na 3 V 2 (PO 4 ) 3 exhibits a structure as a Na superionic conductor, displaying outstanding thermal stability and notable energy density. Whereas conventional preparation process of Na 3 V 2 (PO 4 ) 3 emits harmful gases such as nitrogen oxides and sulfur dioxides, which not only pollute the environment but also escalate material production costs, rendering it unsuitable for large-scale industrial applications. In this work, we successfully synthesized a carbon-coated Na 3 V 2 (PO 4 ) 3 material via spray drying using vanadium oxide (V 2 O 5 ), oxalic acid (H 2 C 2 O 4 ), and sodium dihydrogen phosphate (NaH 2 PO 4 ). Importantly, our production process does not involve the emission of nitrogen oxides and sulfur dioxides, effectively mitigating environmental pollution. The NVP/C−Na sample demonstrates a noteworthy initial capacity of 109.3 mA h g −1 at 1 C. After 5000 cycles at a high rate of 10 C, the material exhibits exceptional cycling stability, maintaining a substantial capacity of 88.4 mA h g −1 . These results underscore its excellent electrochemical performance of the NVP/C−Na, indicating its promising potential for large-scale energy storage in sodium-ion batteries.

Na4Fe3(PO4)2P2O7 cathode exhibits extensive potential for high‐power applications, owing to its large sodium ion diffusion channels, low cost, and suitable operating voltage. However, it suffers significant capacity degradation due to the inevitable NaFePO4 impurity. Herein, a synergistic strategy is proposed that integrates high entropy doping with Fe vacancy engineering, which not only preserves the phase purity but also provides additional active sites and further stabilizes its crystal structure. A novel Na4Fe2.61(Ni, Co, Mn, Cu, Zn, Mg)0.05(PO4)2P2O7 cathode has been successfully synthesized by a simple sol‐gel method, which exhibits an ultralong cycle life (over 15000 cycles at 5 A g−1) and outstanding rate capability (61.1 mAh g⁻¹ at 10A g−1). Additionally, a combined solid‐solution and biphasic reaction mechanism in sodium storage process is thoroughly confirmed. Notably, benefiting from the rational design of N/P ratio and well‐matched capacitive contributions, the full cells assembled with hard carbon anodes exhibit superior cycling durability, sustaining over 1000 cycles at a high current density of 1 A g⁻¹ without severe capacity deterioration. Such highly durable full cells with low N/P ratioand common ester‐based electrolytes have never been reported before. The present work offers new perspectives to expedite the commercialization of low‐cost, high‐power‐density sodium‐ion batteries.
