How do we calculate the percentage of the volume expansion of Si anodes using the cross-section SEM images analysis?

31 January 2022 0 8K Report

I have already analyzed the thickness of a Si anode by cross-sectional SEM image at fresh, lithiated and delithiated states, however, I would like to calculate the volume expansion percentage of the anode. Is there anyone who can explain how we should proceed with this matter? Thanks!
