Reversible ion storage and fast ion transport are critical processes in advanced energy storage systems. In this series of studies, we investigate functional inorganic and organic electrode materials, as well as inorganic/organic composite solid electrolytes, to elucidate their storage mechanisms and transport characteristics.[1-6] Comparative analysis reveals that inorganic electrodes offer robust structural stability and fast ion insertion/extraction kinetics, organic electrodes provide flexible redox-active sites and tunable ion-binding environments, and hybrid solid electrolytes synergistically combine the advantages of both to facilitate low-barrier ion migration and enhanced interfacial charge transfer. By systematically correlating material composition, architecture, and ion dynamics, this series of studies provides fundamental insights and design principles for high-performance electrodes and solid electrolytes, highlighting the potential of tailored organic, inorganic, and hybrid materials for next-generation rechargeable batteries.
