Abstract The cyclability of aqueous zinc‐ion batteries is greatly influenced by Zn dendrites and parasitic reactions. Although separator modifications have proven to be effective in addressing these issues, most the developed separators are too thick meet practical requirements. Herein, an amino (−NH 2 )‐functionalized Zr‐based metal–organic framework (MOF), i.e., UiO‐66‐NH , incorporated into lignocellulose separator. functional groups not only possess good zincophilicity but also strongly interact with H O molecules through hydrogen bonding. Therefore, abundant intersecting subnano‐sized channels within act as desolvation sieves facilitate migration uniform distribution 2+ ions. Even at a rather low thickness 20 µm, modified can significantly improve reversibility electrochemistry suppress water‐induced evolution. With use this separator, electrodes demonstrate working life exceeding 2000 h current density mA cm −2 remarkable dendrite‐free characteristic remain operationally viable under ultrahigh areal capacity 25 mAh . Additionally, resultant Zn//MnO battery provides superior rate capability excellent cyclability. This study novel insights utilization inhibit unfavorable phenomena batteries.

Nonaqueous Li metal batteries (LMBs) and aqueous Zn (ZMBs) are promising next-generation secondary owing to their high energy density. Selecting an appropriate electrolyte is critical for addressing the safety issues nonaqueous can encounter. Ionic liquids (ILs) have been widely used in because they non-flammable, present good thermal stability, wide electrochemical windows. This review highlights research progress on IL-based electrolytes stable Li/Zn anodes. We focus particularly these electrolytes' electrochemistry functionalities at electrolyte/anode interface inhibiting dendrite growth, preventing side reactions, enhancing performance. It expected that this will shed some light development of ILs batteries.
