Description: In this joint Webinar, we report on in situ and in operando imaging of a Li-ion battery sample using a Dimension Icon AFM in a glove box at < 1 ppm O2 and H2O. Using PeakForce Tapping with its direct, pN level force control, we obtain high resolution images of the extremely fragile SEI layer formed upon cycling on the Si anode. This allows us to investigate the formation, evolution, and failure mechanisms of the SEI layer on patterned Si island structures, showing for the first time the in opera
