Abstract Three‐dimensional (3D) carbon materials are often used as carriers for anchoring iodine in zinc‐iodine batteries (ZIBs). However, the physical stacking of during electrode assembly process, weaker interactions between non‐polar and species, scarcity catalytic sites conversion led to a reduced activity redox reaction, which fails completely inhibit shuttling species. Here, 3D ultrafine Cu‐anchored CNT‐rGO (3D Cu@CNT‐rGO) with interconnected structures prepared using simple laser‐induced reduction strategy. The microporous structure excellent electrical conductivity Cu@CNT‐rGO make it an ideal host iodine. Ultrafine Cu nanoparticles introduce catalysts accelerate kinetics, efficiently catalyze iodine/polyiodide conversion, polyiodide shuttling, enhance electrochemical performance ZIBs. fabricated zinc‐iodide micro‐batteries (ZIMBs) delivers high specific area capacity 1.29 mAh cm −2 , energy density (1.55 mWh ) power (33.58 mW well cyclin stability (80% retention after 4000 cycles). Meanwhile, ZIMBs have mechanical flexibility great potential application field integrated, miniaturized flexible electronic devices.
