A kind of modified graphene composite material and super capacitor |
| abstract |
The invention discloses a modified graphene composite material and a super capacitor. The preparation of the modified graphene composite material includes the following steps: performing redox treatment on graphite to prepare graphene oxide powder; further modifying the graphene oxide treatment to obtain graphene powder with high specific surface; by covalently linking sub-fuchsine base to graphene powder with high specific surface, a modified graphene composite material is obtained; supercapacitor, including using sub-fuchsine base@high specific surface The graphene composite material is used as the electrode material to prepare the working electrode. The supercapacitor obtained after assembly has high specific capacitance and good cycle stability. After 10,000 cycles, the capacitance retention rate is above 90%. |
