Zinc–iodine (Zn–I2) batteries have received widespread attention due to their higher safety, rich resources, and eco-friendly features show a promising potential for large-scale energy storage. Nevertheless, challenges such as the shuttle effect of polyiodides sluggish redox kinetics iodine species during charge discharge processes hinder development. This work reports an effective strategy improve electrochemical performance Zn–I2 through size engineering nickel nanoparticles on biomass carbon. In situ UV in Raman spectroscopies reveal that dual-template enables catalyst provide more active sites adsorption catalysis species, thereby enhancing capacity accelerating I–/I2 conversion reaction. The is also significantly inhibited. Consequently, with size-reduced host cathode exhibit superior rate performance, low polarization, long cycle life.

Abstract The practical application of lithium‐sulfur (Li‐S) batteries is severely impeded by poor cycling performance arising from sluggish redox kinetics and the shuttle effect polysulfides. In this work, novel transition metal phytates are pioneered to functionalize conductive carbon address these key limitations. Among a series evaluated, Fe‐Phytate‐modified (Fe‐PA@CB) demonstrates superior specific capacity rate performance. unique molecular‐level Fe‐PA coating ensures uniform dispersion increased active site, leveraging optimized adsorption enhanced catalytic properties. Consequently, activation energy for polysulfide conversion significantly reduced, polarization potential minimized. Fe‐PA@CB electrode improved stability, retaining 61% initial after 500 cycles, compared 40% retention conventional carbon‐based cathode. This work not only provides solution enhancing electrochemical Li‐S but also offers valuable insights into material design mechanistic understanding, paving way development next‐generation storage systems.
