Abstract
An ion-conducting structure comprises a metal-fibril complex formed by one or more elementary nanofibrils. Each elementary nanofibril can be composed of a plurality of cellulose molecular chains with functional groups. Each elementary nanofibril can also have a plurality of metal ions. Each metal ion can act as a coordination center between the functional groups of adjacent cellulose molecular chains so as to form a respective ion transport channel between the cellulose molecular chains. The metal-fibril complex can comprise a plurality of second ions. Each second ion can be disposed within one of the ion transport channels so as to be intercalated between the corresponding cellulose molecular chains. In some embodiments, the metal-fibril complex is formed as a solid-state structure.
