Abstract

The electrode/electrolyte interfacial side reaction is a critical issue for aqueous zinc ion batteries (ZIBs). In this study, it presents an innovative electrolyte designed to utilize steric hindrance effects to modulate Zn ion deposition behavior while mitigating undesirable hydrogen evolution reactions. The incorporation of sugar alcohols into the electrolyte facilitates a reconfiguration of the hydrogen bonding network, alters the solvation structure of Zn²⁺ ions, and promotes a rapid desolvation process, resulting in enhanced ion transport kinetics. Additionally, xylitol molecules preferentially adsorb onto the Zn (100) crystalline surface, inducing structural changes and promote Zn (101) growth. Consequently, this electrolyte configuration enables the zinc anode to achieve an impressive operational lifespan of 2100 h and an exceptional Coulombic efficiency of 99.8%. Furthermore, when paired with ZnHCF as the anode, the full cell operates at a high voltage of 1.75 V, illustrating a promising pathway for the practical application of ZIBs.
