Scalable and Sustainable Chitosan/Carbon Nanotubes Composite Protective Layer for Dendrite‑Free and Long‑Cycling Aqueous Zinc‑Metal Batteries

Caption

  • A sustainable protective layer for Zn anodes integrating carbon nanotubes (CNTs) and chitosan via a simple scraping process to inhibit dendrite growth and side reactions.
  • Chitosan’s polar functional groups enhance Zn2+ transport, and the even distribution of CNTs lowers local current density, enabling a uniform electric field to regulate Zn deposition.
  • Benefiting from the chitosan/CNTs protective layer, the Zn//Zn and Zn//V2O5 cells showcase significantly enhanced electrochemical performance, and technical economic analyses demonstrate their practical applications.
