Abstract
The discovery and design of versatile high-entropy electrolytes are instrumental in enabling advanced aqueous energy storage devices. Precisely regulating the intermolecular forces of anion-cation, ion-dipole and dipole-dipole, which enhance the microscopic disorder of electrolytes, is the core of high-entropy aqueous electrolyte research. In this perspective, the progress in reshaping the electrolyte structure and constructing high-entropy aqueous electrolytes via additional salt or/and solvent engineering is briefly outlined. Further, the next chapter of high-entropy aqueous electrolyte design and optimization is proposed to provide guidance for the development of future high-performing and multi-functional aqueous batteries.
