Abstract Aqueous zinc (Zn) metal batteries (ZMBs) have received extensive attention as potential energy storage systems due to their inherent safety and low cost. However, the practical applications of ZMBs been hindered by parasitic side reactions Zn dendrite formation, undermining efficiency anodes. With continuous research on interfacial chemistry in ZMBs, increasing interest is begun focus achieving dendrite‐free electrodeposition constructing a stable separator/electrode interface. In this report, phthalocyanine (Pc)‐modified glass fiber (Pc‐GF) separator proposed enhance improve stability electrode. This functionalized Pc‐GF can coordinate with during plating construct an electrostatic field layer balance electric ion flux, facilitating electrodeposition. Consequently, symmetric cell using perform 700 h plating/stripping at 2.0 mA cm −2 /2.0 mAh . Moreover, Zn//I 2 full exhibites capacity retention 89.0% after 500 cycles 0.5 C operation 5.0 for 6000 cycles. approach provides effective strategy achieve electrode/separator interface aqueous ZMBs.
