In-Situ, In-Operando PeakForce Tapping Imaging of Li-Ion Batteries in a Glovebox

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.
Presented by: Xingcheng Xiao, Staff Researcher, GM Global R&D Center; Teddy Huang, Senior Application Scientist, bruker Nano Surfaces; and Ravi Kumar, Sheldon Lab, Brown University (August 2, 2016)
