Combining Electrochemistry and Microscopy
In our lab, we established a few experimental setups that can perform electrochemical measurements and optical microscopic observations simultaneously. This allows us to identify the region of interests for further detailed analysis and characterizations. We also have a complete workstation for preparing metallographic samples and a glovebox for the battery study. If you're interested in doing any of these experiments or using our instruments, feel free to contact us.
