Understanding charge transport dynamics in these materials is crucial for optimising device performance. This study investigates the transient charging behavior of three representative MIEC systems: PEDOT:PSS, electrochromic WO3, and n-doped PBDF polymer films via electrochemical impedance spectroscopy (EIS) and transient current measurements, focusing on anomalous diffusion. By employing the transmission line model and fractional exponent fitting, a strong correlation is revealed between impedance response and transient current dynamics. The findings provide insights into the role of fractional diffusion in MIEC charge transport and inform the design of advanced electrochemical devices.The work was funded by the European Research Council (ERC) via Horizon Europe Advanced Grant, grant agreement no 101097688 ("PeroSpiker").
