Abstract:
Zn anodes face dendrite, hydrogen evolution reaction, and corrosion issues. Inspired by the pediatric dental practice of fluoride varnish application for caries prevention, a biomimetic nano-fluoride coating was developed to isolate the Zn anode from the corrosive zinc salt solution, which significantly enhances the efficiency and lifespan of aqueous Zn-ion batteries.
