Batteries and Interfacial Charge Transfer
Properties of the electrified solid/liquid interfaces determine the performance of many energy conversion and storage devices such as batteries, fuel cells, or electrolyzers through the influence on the interfacial charge transfer. One example is intercalation, which is a key process in Li-ion or Na-ion batteries. The rate with which an ion is transferred from the liquid to the solid phases is determined not only by the bulk electrode (or electrolyte) properties but also by the properties of the interface itself.
Our research aims at elucidating physical models of the electrified interfaces in order to design more efficient systems for energy applications.
