There are several electrochemical techniques which can be used to measure the interfacial charge-transfer resistance of LIB AMs at high current densities. These techniques can be separated into three general classes: those which use direct current (i.e., chronopotentiometry), those which use alternating current (i.e., EIS), and those which use a superposition of the two (i.e., operando EIS). In this work, we employ four electrochemical techniques: PEIS, S3E-CP, LA-GEIS, O-GEIS. A general overview of each electrochemical technique is provided in the following section.
