Front Cover: Interfacial Preferential Adsorption and Molecular Mobility Restriction Enabling 3.2 V High Voltage Supercapacitor (ChemPlusChem 10/2025)

To enhance the operating voltage window of supercapacitors (central part), electrolyte engineering (bottom part) is implemented. Ethylene carbonate (EC, white balls) with superior electrochemical stability preferentially absorbs onto the activated carbon electrode (gray, left part). Meanwhile, EC restricts the molecular mobility of fragile acetonitrile (AN, green rugby-ball) through strong interactions（right part). The AN decomposition is effectively avoided and the systematic stability is enhanced.
