Abstract

Two experiments are presented to introduce students to the utility of electrochemical impedance spectroscopy (EIS) in finding electrodes suitable for applications such as battery development. We used different metal and carbon nanotube (CNT) screen-printed electrodes (SPEs) and compared EIS with cyclic voltammetry (CV) curves. In addition, we prepared the SPEs with graphene powder to show the different behaviour of modified and unmodified SPEs with CV and EIS.
