▸　Physics-Based Simulation of Electrochemical Impedance Spectroscopy of Complex Electrode Microstructures

❝　Electrochemical impedance spectroscopy (EIS) is a non-destructive characterization technique widely used in the electrochemical research field. It can measure many macroscopic properties such as internal resistance, capacitance, and diffusivity by fitting the obtained impedance with equivalent circuits. Each of the acquired quantities reflects an electrochemical mechanism, e.g., charge-transfer reaction, double layer formation, and mass transport, taking place in the electrode. However, the obtained quantity is a total value for the whole electrode. The underlying connections between the macroscopic properties, intrinsic material parameters, and electrode microstructures are not well understood. This talk introduces a modeling framework to simulate EIS processes with given electrode microstructures and intrinsic material parameters. With this simulation tool, we provide a digital bridge between battery electrode material properties, electrode microstructures, and their corresponding EIS impedance. 　❞
