The use of electrolyte additives is an efficient approach to mitigating undesirable side reactions and dendrites. However, the existing do not effectively regulate both chaotic diffusion Zn2+ decomposition H2O simultaneously. Herein, a dual-parasitic method introduced address aforementioned issues by incorporating 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIm]OTf) as cosolvent into Zn(OTf)2 electrolyte. Specifically, OTf– anion parasitic in solvent sheath decrease number active H2O. Additionally, EMIm+ cation can construct electrostatic shield layer hybrid organic/inorganic solid interface optimize deposition behavior Zn2+.

Aqueous zinc (Zn) metal batteries (ZMBs) have received great attention due to their safety and environmental friendliness. Although aqueous electrolytes facilitate fast kinetics in oxide cathodes, incompatibility with the Zn anodes triggers severe hydrogen evolution reaction (HER) dendrite growth. Herein, a self-phase separated electrolyte (SPSE) is proposed fulfill contradictory requirements of anode cathode ZMBs. Molecular modeling experimental investigations verify that hydrophobic fluorinated solvent moderate dielectric constant large Hildebrand parameter disparity relative water contributes spontaneous aqueous–nonaqueous phase separation within SPSE against stirring aging. In as-developed SPSE, nonaqueous effectively inhibits HER formation by synergistic effect regulated deposition protective solid interphase (SEI). Meanwhile, ensures ion insertion/extraction dynamics. Consequently, allows for Zn||Zn symmetrical cells 2500 h cycle life ultralow corrosion current (0.08 mA cm–2). Notably, Zn|SPSE|V2O5 full cell sustains over 3000 cycles negligible corrosion, pouch demonstrates remarkable operation stability repeated rollover.
