Zinc-ion batteries are promising for large-scale electrochemical energy storage systems, which still suffer from interfacial issues, e.g., hydrogen evolution side reaction (HER), self-corrosion, and uncontrollable dendritic Zn electrodeposition. Although the regulation of electric double layer (EDL) has been verified principle to select additive as regulator is misted. Here, several typical amino acids with different characteristics were examined reveal behaviors in regulated EDL on anode.

Abstract Along with the booming research on zinc metal batteries (ZMBs) in recent years, operational issues originated from inferior interfacial reversibility have become inevitable. Presently, single‐component electrolytes represented by aqueous solution, “water‐in‐salt,” solid, eutectic, ionic liquids, hydrogel, or organic solvent system are hard to undertake independently task of guiding practical application ZMBs due their specific limitations. The hybrid modulate microscopic interaction mode between Zn 2+ and other ions/molecules, integrating vantage respective electrolyte systems. They even demonstrate original mobility pattern chemistries mechanism distinct electrolytes, providing considerable opportunities for solving electromigration problems ZMBs. Therefore, it is urgent comprehensively summarize principles, characteristics, applications various employed This review begins elucidating chemical bonding physicochemical theory, then systematically elaborates structure, migration forms, properties, mechanisms at anode/cathode interfaces each type electrolytes. Among which, scotoma amelioration strategies current actively exposited, expecting provide referenceable insights further progress future high‐quality

Abstract The instability of the solid electrolyte interface (SEI) is a critical challenge for zinc metal anodes, leading to an erratic electrode/electrolyte and hydrogen evolution reaction (HER), ultimately resulting in anode failure. This study uncovers that fluorine species dissolution root cause SEI instability. To effectively suppress F − dissolution, introduction low‐polarity molecule, 1,4‐thioxane (TX), proposed, which reinforces stability fluorine‐rich SEI. Moreover, TX molecule has strong affinity coordinating with Zn 2+ adsorbing at interface, thereby diminishing activity local water consequently impeding dissolution. robust layer promotes high durability repeated plating/stripping cycles, while concurrently suppressing HER enhancing Coulombic efficiency. Notably, symmetric cell demonstrates exceptional electrochemical performance, sustaining over 500 hours 20 mA cm −2 10 mAh . Furthermore, Zn||KVOH full exhibits excellent capacity retention, averaging 6.8 98 % retention after 400 even loading lean electrolyte. work offers novel perspective on as key factor failure, providing valuable insights design energy storage devices.
