Polymer-Metal Oxide Cluster Co-Crystallization for the Synergy of Superionic Conduction and Mechanical Robustness.
Solid polymer electrolytes (SPEs) promise high safety for next-generation energy storage, but practical applications are bottlenecked by the coupling of ion transport with sluggish polymer segmental dynamics. Herein, polymers are co-crystallized with sub-nm anionic metal oxide clusters (MOCs) using Li+ counterions, ach...
