A Self-Phase Separated Electrolyte toward Durable and Rollover-Stable Zinc Metal Batteries

Abstract
Aqueous zinc (Zn) metal batteries (ZMBs) have received great attention due to their safety and environmental friendliness. Although aqueous electrolytes facilitate fast kinetics in metal oxide cathodes, their incompatibility with the Zn metal anodes triggers severe hydrogen evolution reaction (HER) and dendrite growth. Herein, a self-phase separated electrolyte (SPSE) is proposed to fulfill the contradictory requirements of the anode and cathode in ZMBs. Molecular modeling and experimental investigations verify that the hydrophobic fluorinated solvent with moderate dielectric constant and large Hildebrand parameter disparity relative to water contributes to a spontaneous aqueous–nonaqueous phase separation…
