Overview

Randomized trial demonstrates improved charge transfer in sodium vanadium oxide for zinc-ion batteries, indicating greater efficiency and durability.

Key Points

  • This research aims to improve the performance of sodium vanadium oxide cathodes in aqueous zinc-ion batteries through interfacial engineering using PEDOT.
  • Proposed a PEDOT-regulated strategy for modifying sodium vanadium oxide nanostructures.
  • Conducted kinetic analyses to evaluate charge storage behavior and Zn2+ diffusion.
  • Performed ex situ XRD and SEM for structural assessments during Zn2+ cycling.
  • The 1P-NaVO cathode achieved 655 mAh g−1 at 0.1 A g−1, reflecting enhanced capacity.
  • Low charge transfer activation energy measured at 20.6 kJ mol−1 indicates better electron transfer efficiency.
  • Zn2+ diffusion coefficients ranged from approximately 10−10.8 to 10−9.8 cm2 s−1, showing improved ionic transport.
