Dr. Christoffer Karlsson, Senior R&D Scientist at rhd instruments, presents electrochemical impedance spectroscopy (EIS) measurements, focusing on battery component properties such as the MacMullin number of separators, tortuosity of active material coatings, and electrolyte conductivity. He also discusses a workflow for simple and reliable impedance data fitting and parameter evaluation.
Electrochemical Impedance Spectroscopy: Detailed information about complex systems
Electrochemical impedance spectroscopy (EIS) is a widely used multidisciplinary technique for characterizing the behavior of complex electrochemical systems. EIS performed on cells containing only the essential components can provide detailed information about each part of the device. This approach allows for a clearer distinction of each component's contribution to the overall performance. It also helps explain the electrochemical behavior of the complete system.
