Electrochemical processes are uniquely complex, especially in the confinement of nanopores and in regards to structural changes during ion insertion / intercalation. Our team, in close collaboration with collaborators, employs (1) in situ small angle scattering, (2) electrochemical dilatometry, (3) electrochemical quartz crystal microbalance with dissipation monitoring, (4) in situ Raman spectroscopy, and (5) nuclear magnetic resonance spectroscopy.
