Rubidium could be the next key player in oxide-ion conductors. Researchers have discovered a rare rubidium (Rb)-containing oxide-ion conductor with exceptionally high conductivity. Identified through computational screening and experiments, its superior performance stems from low activation energy and structural features like large free volume and tetrahedral motion. Its stability under various conditions offers a promising direction for solid oxide fuel cells and clean energy technologies.
