Summary: This paper focuses on improving the electrochemical performance of Sodium Vanadium Oxyfluorophosphate (NVPFO), a high-stability, high-capacity, and high-voltage cathode material for sodium-ion batteries, by doping it with Zr4+ ions. A series of Na3V2-xZrx(PO4)2F2O compounds are prepared, and the successful doping of Zr4+ is confirmed through various characterization techniques. The optimal doping concentration of 4 at% results in Na3V1.96Zr0.04(PO4)2F2O, which exhibits a specific capacity of 128, 106, 85, and 55 mA h g-1 at different current rates. Additionally, the doped material shows improved cycling stability and a higher Na+ diffusion coefficient compared to the undoped NVPFO.

Summary: Sodium-ion batteries (SIBs) are emerging as a promising alternative to Lithium-ion batteries (LIBs) for energy storage systems. This study presents a strategy to enhance SIBs performance by cross-linking NVPF with multi-dimensional nanocarbon frameworks composed of amorphous carbon and carbon nanotubes (NVPF@C@CNTs). The unique structure of NVPF@C@CNTs ensures shortened sodium ion transmission pathway and improved electronic transfer network, resulting in enhanced charge transfer kinetics and superior cycling stability. The obtained electrochemical properties, including high specific capacity and long-term cycling stability, demonstrate the potential of NVPF@C@CNTs for large-scale energy storage applications.

Summary: Reconstructing the inner Helmholtz layer (IHL) by introducing an electrolyte additive is a promising strategy to obtain stable Zn metal anodes in aqueous zinc ion batteries (AZIBs). The addition of (4-chloro-3-nitrophenyl) (pyridin-4-yl) methanone (CNPM) to the ZnSO4 electrolyte reshapes the Zn metal anode/electrolyte interface and changes the solvation structure of Zn2+. The CNPM adsorbs on the Zn anode surface and serves as zincophilic sites, leading to uniform Zn deposition along the (002) plane and suppressing dendrite growth and parasitic reactions.
