EIS for a Lithium-Ion Battery

Please login with a confirmed email address before reporting spam

Hello everyone,

Im trying to build a Lithium-Ion Battery model to get the Electrochemical Impedance Spectroscopy for a full cell and estimate some parameters like the exchange current density, the film resistence, the double-layer capacitance, the charge transfert resistance and the diffusivity of the lithium ion in the electrode in both electrodes. I found some tutorials about this topic: https://www.comsol.de/model/modeling-impedance-in-the-lithium-ion-battery-17809

The problem is that the studies in this app are only done on the postive electrode, my goal is to study and get thoose parameters for the hole cell. I need some help please, im doing my bachelor-thesis and running out of time, i can pay for the efforts when needed !

Regards Borhen
