some of the applications of EIS includes detecting corrosion of metals, characterizing aging of food, measuring bacterial concentration in label-free biosensors, and studying ion mobility in batteries and supercapacitors.
I suggest you to have a look at the following paper/note:
- A method based on impedance spectroscopy to determine transport properties of polymer electrolytes
A. K. Arof, S. Amirudin, S. Z. Yusofa and I. M. Noora
Physical Chemistry Chemical Physics, Issue 5 (2014)

- Basics of Electrochemical Impedance Spectroscopy

You will certainly be able to find more specific literature, linked to your experimental needs.
I agree with both. I think you need to specify what "mobility" means. I think you want to get charge carrier mobility as cm2/(V*s). There is paper that may help Article Charge carrier mobility and lifetime of organic bulk heteroj...
