Nature Communications (2026). DOI: 10.1038/s41467-026-70322-5"> Transition from a 'camel-shaped' to a 'bell-shaped' curve caused by changes in the electric double-layer structure. Credit: Nature Communications (2026). DOI: 10.1038/s41467-026-70322-5 From smartphone charging to hydrogen production, the fundamental principles of energy technology have been revealed. Korean researchers have, for the first time, identified how molecular structures change within the ultra-small space called the "electric double layer." The study, published in the journal Nature Communications , opens a new path to simultaneously improve efficiency and performance in battery, hydrogen, and carbon-neutral technologies by reducing energy loss and selectively inducing desired reactions.…
