Electrostatic Confinement of Polyiodides by Cationic Biomass-Binder Toward High-Performance and Sustainable Aqueous Zinc-Iodine Batteries.
Aqueous zinc-iodine batteries (AZIBs) hold great promise for sustainable energy storage, yet their practical viability is hindered by the uncontrolled shuttling of soluble polyiodide intermediates (e.g., I3 - and I5 -), which causes severe cathode active-material loss and zinc anode corrosion. Herein, hydroxypropyl tri...
