Vortrag im Rahmen der Chemisch Physikalischen Gesellschaft

Electrochemical solid|liquid interfaces are critically important for materials for energy storage, harvesting, and conversion, and for material stability in general. Yet, a real-time visualization of dynamic processes at electrified solid|liquid interfaces with close to atomic resolution is extremely challenging. Processes such as an electrochemical surface modification, or localized surface reactions in confinement are inherently diffi-cult to visualize in real time with micro-to-nano scale resolution.
In this presentation I will highlight recent advances in characterizing electrochemical interfaces with the electrochemical surface forces apparatus (EC-SFA) and high-reso-lution AFM imaging and force probe studies, ranging from electric double layer char-acterization in ionic liquids, to real-time measurement of corrosion rates in confined localized areas, to electrochemical growth of solid electrolyte interfaces on Li-battery anodes.
