One-dimensional graphene fibers ( GFs ) possess excellent properties, including high electrical conductivity, good physical and chemical stability, high thermal conductivity, flexibility, etc. GFs are ideal electrode materials for fiber-shaped supercapacitors. However, due to the lack of an effective method to manufacture GFs with high specific capacitance, their low energy density hinders their practical application. Herein, we decorated wet-spun graphene oxide fibers ( GOFs ) by dip-coating them with graphene oxide ( GO) solutions containing different contents of lignin to obtain a core-sheath lignin/GO composite fibers. After carbonization and activation, we successfully prepared lignin derived carbon/GF electrodes. The assembled fiber-shaped supercapacitors ( FSSCs ) exhibit a specific capacitance of 9. 98 mF/cm2 and an energy density of 0.89 μW·h/cm2 , about 6 times of those of pure GFs (1.57 mF/cm2 and 0.14 μW·h/cm2, respectively), long cycling life and cycling stability. This suggests that the introduction of lignin derived carbon into GFs can effectively increase the specific capacitance and the energy density of FSSCs.
