Abstract
Significance In situ characterization of kinetics at electrode–electrolyte interfaces (EEIs) is crucial to the rational design of efficient and sustainable solid-state electrochemical technologies. A significant advancement has been made to rationally understand processes at EEIs using solid-state in situ thin-film electrochemical cells fabricated using specially designed ionic liquid membranes with excellent mass-transfer properties. The in situ cells are used to characterize well-defined EEIs generated using ion soft-landing (SL) in controlled environments, both in vacuum and in the presence of reactant gases. Populating EEIs with precisely defined electroactive species using SL facilitates molecular-level understanding of electron transfer processes within deposited species and between species and electrodes, thus providing a powerful methodology to characterize technologically relevant EEIs during operation.
