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 that synergistically integrate conductive rGO, POM, and polymer networks, enhancing the iodine immobilization and kinetics in Zn–I₂ batteries and thus achieving high capacity (225 mAh g⁻¹) and stability (84.5% retention after 3000 cycles).
