Anionically-Reinforced Nanocellulose Separator Enables Dual Suppression of Zinc Dendrites and Polyiodide Shuttle for Long-Cycle Zn-I2 Batteries

Highlights Straw-derived carboxylated nanocellulose separator is modified by anionic polyacrylamide to further enhance the negative charge density. The separator exhibits ultrathin profile and exceptional mechanical strength, as well as enabling rapid zinc ion transport. The separator can not only e...
