Eine Interphase mit ortsfesten Ladungen synchronisiert den Ionentransport und unterdrückt raumladungsgetriebene Ineffizienz unter räumlicher Begrenzung auf Nanoliter‐Volumina

Angewandte Chemie, EarlyView.
Die elektrochemische Energiespeicherung stößt bei extremer Miniaturisierung an fundamentale Grenzen, da Grenzflächen‐ und Raumladungseffekte dominieren. Hier stellen wir eine selektive Interphase mit ortsfesten Ladungen in einer Zwillingsrohr‐μ‐Swiss‐Roll‐Architektur vor.
