Accessing Battery Material Properties with Electrochemical Techniques

Electrochemical methods are useful for determining various material properties of the components in electrochemical devices. Specifically, electrochemical impedance spectroscopy (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.
In this webinar, Dr. Christoffer Karlsson will show some examples of this methodology, focusing on battery component properties such as the MacMullin number of separators, tortuosity of active material coatings, and electrolyte conductivity. A workflow for simple and reliable impedance data fitting and parameter evaluation will also be shown.
