Anchoring Polyiodides: Microphase-Separated Gel Polymer Cathode for Zinc–Iodine Batteries

Abstract Zinc–iodine (Zn-I2) batteries are attractive for grid-scale energy storage owing to safety and low cost, yet practical deployment is hindered by shuttling of soluble polyiodide intermediates (I3–, I5–), which causes capacity decay, anode corrosion, and thermal instabilit...
