“…[ 26 ] Due to ion‐solvent coordination environment differences, the influence of the same organic solvent on different metal potential shifts could be different. [ 23,27 ] For AZBs, due to the presence of water molecules, the potential downshift of the Zn anode could company with the HER. Therefore, the chosen organic solvent (coordination agent) should simultaneously possess appropriate properties to regulate the Zn 2+ solvation sheath and inhibit the HER.…”

Mild aqueous Zn batteries (AZBs) generally suffer a low‐voltage/energy dilemma, which compromises their competitiveness for large‐scale energy storage. Pushing Zn anode potential downshift is an admissible yet underappreciated approach for high‐voltage/energy AZBs. Herein, with a mild hybrid electrolyte containing in situ‐derived diluted strongly‐coordinated Zn2+‐cosolvent pairs, a considerable Zn anode potential downshift is initially achieved for high‐voltage Zn‐based hybrid batteries. The chosen butylpyridine cosolvent not only strongly coordinates Zn2+ ions but also acts as a hydrogen‐bond end‐capping agent to inhibit hydrogen evolution reaction (HER). The electrolyte environment with hetero‐solvation‐diluted strongly‐coordinated Zn2+‐cosolvent pairs remarkably lowers Zn2+ activity, responsible for the Zn electrode potential downshift (−0.330 V vs Zn), confirming to modified Nernst law (ΔE = ln[a(Zn2 + )/a(coordinated solvent)]). With the diluted Zn2+‐containing hybrid electrolyte, the Zn//Zn symmetric cell in the hybrid electrolyte shows a long lifespan over 1270 h at a stripping/plating capacity of 0.4 mA h cm−2. Compared with in common hybrid electrolytes, the as‐assembled Zn‐MnO2 hybrid battery delivers a ca. 0.278 V enhanced voltage plateau (1.57 V) and a long‐term cyclability of over 736 cycles. This work opens a new avenue toward Zn anode potential downshift for high‐voltage AZBs, which can extend to other mild metal batteries.

“…Due their reasonable conductivity properties and electrochemical window, ionic liquids have been studied as media or as supporting electrolytes for electrochemical studies (18)(19)(20). Then there is the possibility to reduce metal ions, contained in an ionic liquid phase to form a metallic deposition with certain characteristics.…”
