Nitrogen and fluorine co-doped graphene as a high-performance anode material for lithium-ion batteries

Nitrogen and fluorine co-doped graphene (NFG) with the N and F content as high as 3.24 and 10.9 at% respectively was prepared through the hydrothermal reaction of trimethylamine tri(hydrofluoride) (C 2 H 5 ) 3 N·3HF and aqueous-dispersed graphene oxide (GO) as the anode material for lithium ion batteries (LIBs).
