A novel carbonized natural silk nanofiber/graphene oxide aerogel for supercapacitor

In this study, we established a novel electrode material for supercapacitors using carbonizing natural silk nanofibers/graphene oxide (SNF/GO) aerogel. Particularly, the SNF/GO electrode fabricated at 800°C carbonization exhibited unique microstructure, high stability. In terms of its electrochemical performances, the 800°C SNF/GO electrode showed lower resistance and higher capacitance. After 10000 cycles of charging, the 800°C SNF/GO supercapacitor presented remarkable capacitance stability, indicating great potential in supercapacitor and other energy storage systems.
