▎ 摘 要
Nano-sized FeF3/graphene composite has been prepared by a one-pot method. The product shows a significantly improved cycling stability and rate capability comparing with pristine FeF3. The results show that the ultrafine particle size of the composite and the tight contact between graphene and FeF3 are the main reasons for the enhanced electrochemical performance.
