Electron Donation Effect of α‐Boron Nanosheet Enables Highly Stable Zinc Metal Anode

Abstract Efficiently inhibiting dendrite growth and water‐induced side reactions on Zn metal anode still remains a great challenge for the practical application of aqueous Zn ion batteries (AZIBs). Herein, an α‐boron nanosheet‐coated Zn foil (α‐B@Zn) is presented, aiming at enhancing the performance and stability of Zn metal anodes. The α‐B nanosheets are successfully synthesized via ultrasonic treatment, exhibiting a unique 2D morphology. Thanks to their hydrophobic and insulating properties, the α‐B coating significantly mitigates the hydrogen evolution reaction (HER) and surface corrosion. Furthermore, theoretical calculations and experimental results reveal that the α‐B layer facilitates the electron…
