Summary: Recent research has shown that NASICON-type compounds, typically considered ideal candidates for AZIBs due to their large ionic channels and fast kinetics, may not be suitable after all due to their structural instability. Two NASICON structures, Na3V2(PO4)(3) and Na3V2(PO4)(2)F-3, were found to undergo structural decomposition in 1 M Zn(CF3SO3)(2) electrolyte during repeated cycling, with Na3V2(PO4)(3) degrading into Zn3V2O8, V2OS, and VO2 and Na3V2(PO4)(2)F-3 decomposing into V2O5, VPO5, and Zn-3(OH)(2)V2O7 center dot 2H(2)O. The decomposition mechanisms are attributed not only to inherent instability during Zn+ ion (de)intercalation, but also to the coinsertion of H+ and solvation effect of H2O, accelerating the structural decomposition process.

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: Na3V2(PO4)2O2F (NVPOF) is a promising cathode material for sodium-ion batteries (SIBs) due to its high theoretical capacity, stable structure, and high working platform. However, interface problems such as slow reaction kinetics and poor ion storage capacity hinder its application. In this study, NVPOF with interfacial V-F-C bonding (CB-NVPOF) is developed, showing high rate capability and long-term cycling stability. The incorporation of interfacial V-F-C bonding significantly improves electronic conductivity, Na+ diffusion, and interface compatibility at low temperatures (-40 degrees C). This study provides a novel idea for enhancing the electrochemical performance of NVPOF-based cathodes for SIBs at low temperatures.
