The dE/dx corresponds to a single point on the plateau, but which concentration should I choose?

Dan Thien Nguyen

You should measure BET your active material. Based on loading level of your electrode, you can calculate the A. What experimental method did you use for calculating DLi? CVs or GITT, ..etc?

Hi Danthien!

I performed experiments using CVs ang galvanostatic charge-discharge.
