V‐Doping Strategy Induces the Construction of the CoFe‐LDHs/NF Electrodes with Higher Conductivity to Achieve Higher Energy Density for Advanced Energy Storage Devices

Small, Journal Year: 2024, Volume and Issue: 20(44)

Published: July 10, 2024

Doping of metal ions shows promising potential in optimizing and modulating the electrical conductivity layered double hydroxides (LDHs). However, there is still much room for improvement common conventional doping methods. In contrast to previous methodologies, a hollow triangular nanoflower structure CoFeV-LDHs devised, which enriched with greater number oxygen vacancies. This resulted significant enhancement LDHs, leading an increase energy density following appropriate V. To investigate impact V-doping on situ XPS X-ray spectroscopy employed. Regarding electrochemical performance, CoFeV-LDHs/NF electrode optimal ratio exhibited specific capacitance 881 F g
