摘要
Aqueous zinc‐ion batteries (ZIBs) have attracted much attention due to the low cost and high safety. However, sluggish reaction kinetics and poor cycling stability hinder their further application. Herein, a graphene oxide wrapped ZnMnO 3 nanorod (ZMO/GO) is successfully prepared and employed as cathode in ZIBs. Battery with ZMO/GO cathode demonstrates favorable special capacity of 174.8 mAh g −1 at a current density of 0.1 A g −1 and sufficient stability at 2 A g −1 . The superior electrochemical performance may be attributed to the GO with high electrical conductivity and ZMO with fast H + diffusion.
