Abstract

The traditional glass fiber separator exhibits weak interaction with the electrolyte and low transport efficiency, limiting its application in zinc-ion batteries. In this study, we propose a simple approach to construct sulfonated modified separator (GF-SO₃) that facilitates robust ion transport channel for aqueous zinc-ion battery. The strong interaction between SO₃^- and Zn²⁺ cation enhances the embedding of zinc ions in the cathode. When assembled with zinc sheets anode and VOH cathode to form a button cell, the GF-SO₃ separator demonstrates a high specific capacity of 180 mAh/g at 0.5 A/g, maintaining 64.5 mAh/g after 500 cycles at 5 A/g, significantly superior to commercial glass fiber separator.
