This study presents a novel approach to enhance the performance of aqueous zinc-ion batteries (AZIBs) by designing a porous conductive protective layer on the Zn anode using a phase transfer method. The protective layer, denoted as (PVDF (Polyvinylidene fluoride)/CNTs (Carbon Nanotubes)-PT @ Zn), effectively inhibits dendrite formation and side reactions triggered by H₂O, leading to uniform Zn deposition. In-situ characterization, COMSOL simulations, and migration energy barrier calculations demonstrate the effectiveness of the PVDF/CNTs-PT @ Zn layer in improving cycle stability and electrochemical performance. The symmetrical cell using this protective layer shows dendrite-free plating/stripping and superior cycle stability compared to a bare Zn anode. Additionally, the PVDF/CNTs-PT @ Zn anode is coupled with a commercial V₂O₅ cathode to form a stable rechargeable full battery. The study highlights the potential of this protective layer in inhibiting Zn dendrite growth and side reactions, making it a promising solution for the construction of metal anode protection layers in AZIBs.This study presents a novel approach to enhance the performance of aqueous zinc-ion batteries (AZIBs) by designing a porous conductive protective layer on the Zn anode using a phase transfer method.
