The advancement and application of electrochemical energy storage and conversion systems have pushed to extremes for electrified interfaces where many important physical and (electro) chemical processes take place. In one extreme, academic researchers look at the single atom level to facilitate the interfacial reactions (e.g, oxygen reduction reaction) in fuel cells and (photo) electrolyzer. In another extreme, industrial scientists assemble thousands of atoms at solid/solid and solid/liquid interfaces of battery with a goal to deliver high energy density, superior power, and long life. The two directions appear distinct but require the high-performance interfaces under electrochemical conditions. To address the pressing opportunities and challenges, we have designed this symposium to highlight the recent frontiers at electrochemical interfaces for energy systems. The symposium will bridge expertise in academia research and industrial applications from electrochemical deposition, reactions, functional control, advanced characterizations to applications of energy devices. Particular attention will be paid to the understanding of interfacial chemistry, the control, and multimodal operando characterization of materials in catalysts, energy storage and conversion. This topic may also include novel architectures for mechanistic studies, such as the use of epitaxial thin film and single entities as model systems. This symposium will provide an interactive forum for scientists from various fields interested in the application of interfacial engineering to both classical and emerging applications. Specific sessions will be organized based on scientific theme topics to foster cross-fertilization of ideas and strategies. We hope this symposium will benefit materials scientists from various backgrounds, and will help encourage the implementation of rational design, smart control and advanced characterization approaches to solve the needed problems at atomic scale and device level.
