| Abstract: | Oxide graphene material was prepared by Hummers method with nature graphite as raw material. Graphene materi- al was prepared with NaBH4 as reductive additive. The structure and electrochemical performance of graphene were characterized by EIS, X - ray, charge - discharge test, infrared analysis methods. The results showed that the graphene delivered the initial dis- charge capacity of 866.4 mAh g-1 and the initial charge capacity of 305.2 mAh g-1, the coulombic efficicency was 35.2%. |
