How to calculate the Warburg factor (σ),diffusion coefficient of the Li+ (DLi) and ω-1/2 from the Nyquist plot ?

30 April 2020 1 7K Report

Dear researcher,

please explain the simple way to make the plot of Z' vs ω-1/2 to obtain σ ( Warburg factor) from EIS graph ? and what will be the lithium ion concentration (c) (is it constant or vary) to obtain diffusion coefficient of the Li+ (DLi) in the equation given below ?

your resposes are higly appreciated.

Elida De Obaldia

The authors have extracted the values of sigma (the Warburg coefficient) using the Randles circuit. Matt Lacey has a great description and an online simulation http://lacey.se/science/eis/simulation-randles-circuit/. You can use EC-Lab Demo or Zplot to run the simulations.

Once you have the sigma value, you plot it into equation (1) and calculate the diffusion coeffient for Li. Hope this helps.
