Nano/Micro Metal‐Organic Framework‐Derived Porous Carbon with Rich Nitrogen Sites as Efficient Iodine Hosts for Aqueous Zinc‐Iodine Batteries

Abstract Nowadays, the low cost, superior safety, and long durability of aqueous zinc–iodine (Zn–I 2 ) batteries have garnered significant interest. Nevertheless, their practical use is limited by the inferior conductivity of iodine and the shuttle effect, resulting in suboptimal electrochemical behavior. In this work, a nano/micro zinc‐based metal‐organic framework (Zn‐MOF) featuring a cubic morphology is employed for obtaining porous nitrogen‐doped carbon (NC), which is reported as a cathode host for Zn–I 2 batteries. Thanks to its porous architecture and high conductivity of NC, the optimized S3‐1000 material achieves high iodine loading and enables rapid electron/ion transport. More importantly, the…
