Polyoxometalate-Mediated Confined Self-Assembly of Sandwich-Structured Mesoporous Polymer@rGO for High-Performance Aqueous Zinc-Iodine Batteries

Abstract

Here, a polyoxometalate (POM)-mediated confined self-assembly strategy is reported to fabricate sandwich-structured mesoporous polymer@reduced graphene oxide (rGO) nanosheets Synergistically integrates conductive rGO, POM, and polymer networks, enhancing iodine immobilization and kinetics in Zn-I₂ batteries. Achieves high capacity (225 mAh g⁻¹) and stability (84.5% retention after 3000 cycles).
