We show that the ionic and electronic conductivity of a wide range of p-type and n-type conducting polymer thin films can be reliably measured as a function of electrochemical doping in relevant battery electrolytes by impedance spectroscopy on interdigitated electrodes by combining two separate electrode geometries. The results demonstrate the broad applicability of the methodology for gaining insights into the electrical conduction in polymers in relevant environments, particularly for batteries and other electrochemical devices
