Determining the Tortuosity and the Pore Resistance of Porous Lithium-Ion Electrodes using Electrochemical Impedance Spectroscopy via a Gamry Interface 5000E

Determining the Tortuosity and the Pore Resistance of Porous Lithium-Ion Electrodes using Electrochemical Impedance Spectroscopy via a Gamry Interface 5000E

Tortuosity and pore resistance of porous lithium-ion electrodes influence the performance of high-performance lithium-ion batteries. Electrochemical impedance spectroscopy is a fast, powerful and non-destructive tool for the characterisation of the pore resistance of such electrodes, this application note describes this technique.
