Herein, hydroxypropyl trimethyl ammonium chloride chitosan (HTCC), a quaternized biomass derivative, is developed as a cationic binder that fundamentally suppresses the polyiodide shuttle effect. Unlike binders with weak hydrogen bonding that can only immobilize I\n                    <jats:sub>3<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    , HTCC immobilizes both I\n                    <jats:sub>3<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    and I\n                    <jats:sub>5<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    through strong electrostatic interactions, complemented by hydrogen\u2010bonding interactions. The optimized aqueous AZIBs exhibit exceptional antiself\u2010discharge performance, as demonstrated by a stable open\u2010circuit voltage of 1.322\u2009V and a Coulombic efficiency above 96.2% after a 72\u2009h rest. Furthermore, they deliver a highly specific capacity of 216.4\u2009mAh\u2009g\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 0.1\u2009A\u2009g\n                    <jats:sup>\u22121<\/jats:sup>\n                    and outstanding long\u2010term cycling stability, retaining 90.1% of their initial capacity after nearly 40,000 cycles at 5.0\u2009A\u2009g\n                    <jats:sup>\u22121<\/jats:sup>\n                    . Mechanistic studies reveal the functionality of HTCC in mitigating polyiodide shuttling and zinc anode corrosion, owing to substantially enhanced adsorption energies and accelerated iodine conversion kinetics. This work highlights the great potential of cationic biomass binders for high\u2010performance, sustainable aqueous iodine\u2010based energy storage.\n
