In batteries, fuel cells, water splitting/oxygen reduction, and other electrochemical energy storage and conversion systems, effectiveness and stability of the solid-liquid interface is directly correlated to the performance and lifetime of an electrochemical device. A mechanistic understanding of the interfacial reactions and processes occurring at the solid and liquid interface is needed to provide the scientific underpinning for the design of next-generation electrochemical energy storage and conversion devices. This requires technique development for characterization of local structures and non-equilibrium dynamics at interfaces at high spatial resolution (down to nm scale), time resolution (millisecond or lower) and high chemical sensitivity (spanning from light element H, Li, O to heavy metals). Moreover, the direct comparison of experimental results with modeling of the interfacial chemistry under realistic conditions is a key to the basic understanding of complex interfaces.
The goal of this symposium is to create a forum for fundamental understanding about the charge transfer, ionic transport and heterogeneous reactions at these interfaces and the effect of nano-scale, crystal orientations and other various factors on these phenomena. Similarities and differences between batteries, fuel cells, and other electrochemical systems will be highlighted. Abstracts are particularly encouraged on the development of new sample environment and model electrodes of defined orientations and surface structures that allow the imaging of fundamental phenomena and processes occurring at liquid/solid interfaces in operando and permit direct correlation with atomistic modeling.
