Abstract

To enhance the electrochemical stability and kinetics of V₂O₅, 3,4-ethylenedioxythiophene (EDOT) was in situ polymerized within V₂O₅ interlayers, rendering PEDOT@V₂O₅ with enlarged layer spacing, increased stability in organic electrolyte, and superior electrochemical kinetics (bleaching/coloration times 10.9/9.1 s) and cyclability (98.5% ΔT and 85.6% capacity retention after 1000 cycles) in a PEDOT@V₂O₅‖Zn electrochromic device.
