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.
