Zeolite-Filled Glass Fiber Separator Enables Ah-level Zinc Ion Batteries via Synergistic Dual-Electrodes Regulation

Aqueous Zn//V2O5 batteries (ZVBs) hold promise for large-scale energy storage due to their high safety and low cost, but face critical challenges of Zn dendrite growth and parasitic side reactions at the Zn anode, coupled with severe vanadium dissolution and shuttle at the V2O5 cathode. Conventional strategies, such as electrolyte engineering or separator modifications, often focus on single-component optimization, neglecting synergistic anode and cathode regulation. Herein, we developed a Zeolite Socony Mobil-5 (ZSM-5) filled glass fiber separator (ZSM-5@GF) to address these issues simultaneously. The ZSM-5 zeolite facilitates the Zn2+ desolvation via binding H2O molecules, suppressing HER and side reactions.…
