Determination of the Through-Plane Tortuosity of Battery Electrodes by EIS in a symmetric Lithium-iron-phosphate cell
Tóm tắt
In this application note, we demonstrate how to determine the through-plane tortuosity τ of a commercial lithium ion battery cathode material with known porosity and coating thickness, based on the electrochemical impedance spectroscopy (EIS) method.
