Abstract The parasitic reactions and rampant dendrite growth on the Zn anode side pose significant obstacles to future applications of aqueous zinc ion batteries. Herein, a lightweight host is reported by introducing nanosized metallic into poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) (P‐S) aerogel (Zn/P‐S). ‒SO 3 H groups interact with 2+ guild their migrations along PSS chains, while offer additional nucleation sites homogenize electrical concentration. Owing these synergistic effects, uniform dense deposition (002) plane aligned parallel P‐S substrate achieved, even at high plating capacity 20 mAh cm −2 . Moreover, deposited over Zn/P‐S (Zn@Zn/P‐S) exhibits highly reversible plating/stripping behavior Coulombic efficiency maintained 99% 700 cycles. Consequently, Zn@Zn/P‐S‐based symmetric Zn||Zn cell can work stably 500 h 0.5 ‒2 100 4 depth discharge 40%.

Abstract Zinc‐air batteries (ZABs) offer promising forthcoming large‐scale high‐density storage systems and the cost‐effectiveness of electrode materials, specifically in solid‐state liquid electrolytes. However, uncontrolled diffusion utilization irreversible zinc components cell design principles limit practical applications with severe capacity fade interfacial reactions. In this perspective article, aim is to shed lights on underlying mechanisms solid electrolytes interfaces alongside current status prospective research insights. Formulations ampere‐hour (Ah)‐scale cylindrical/pouch cells are discussed for 100–500 Wh kg −1 cell‐level energy metrics under realistic operations. The electrode/electrolyte interface dynamics, scale‐up readiness, testing protocols, key performance also suggested transforming lab‐scale into production.

Covalent Anchoring of Mechanical Polymer for Highly Stable Zinc Metal Batteries

Abstract Artificial interfacial protective coatings (IPCs) on Zn anodes provide a viable solution for suppressing dendritic growth by spatially confining and homogenizing the 2+ flux. However, repeated deformation during electroplating/stripping cycles can lead to rupture or exfoliation of IPCs, as well formation detrimental gaps. Herein, highly durable IPC is developed substrate using mechanically robust fluorinated polyimide nanofilm (FPI). This unique FPI interphase forms strong covalent bonds with through electronegative fluorine atoms, facilitating plating/stripping while maintaining adhesion. The superior resilience, modulus, low creep film resist impact stresses from electroplated Zn, ensuring structural integrity. With this coating, FPI‐Cu||Zn half cells demonstrate high reversibility in over 4000 h, Coulombic efficiency above 99.33%. When coupled MnO 2 cathode, ||FPI‐Zn full exhibit long lifespan, surpassing 5000 cycles, specific capacity retention 75.21%. study highlights importance achieving balance between customized compatibility mechanical properties IPCs modulate zinc chemistries.
