Solid polymer electrolytes (SPEs) hold substantial potential for enabling highly flexible and stable zinc-ion batteries (ZIBs) due to their nearly anhydrous nature. However, the development of SPEs is still hindered by poor zinc-ion-transport kinetics. Herein, utilizing CALF-20 as both a filler functional coating, bilayer solid-state electrolyte (BSSE) was designed. On one hand, intermediate filled poly(ethylene oxide) hybrid gel demonstrates strong interaction with CF3SO3- anions, thus promoting Zn2+ dissociation transmission. other outer single layer supports ions abundant transmission paths low migration energy barrier, which doubly accelerates ion at interface. This internal/surface dual acceleration strategy allows BSSE deliver high ionic conductivity transference number. Both Zn∥Zn symmetric Zn∥MnO2 full cells exhibit an obvious prolonged cycle life. sheds light on design high-ionic-conductivity, steady, practical ZIBs.

Abstract Aqueous zinc‐ion batteries (AZIBs) have become critical in driving the advancement of large‐scale energy storage systems due to their high specific capacity, safety, environmental friendliness, and low cost. However, fundamental challenges associated with Zn anodes, including dendrite growth, hydrogen evolution reaction, corrosion, zinc utilization, significantly hinder improvement cyclic stability density AZIBs. In light these challenges, considerable efforts been devoted exploring stable while a significant gap persists between current research advancements practical working conditions. Therefore, this review first reveals detailed mechanisms formation, as well influence utilization on AZIB systems. addition, recent various modification strategies for improving anodes are summarized, corresponding investigated. Finally, key factors advancing development application AZIBs clarified, goal bridging status future demands.
