Three dimensional heteroatom-doped carbon composite film for flexible solid-state supercapacitors

2019-12-26 12:58:10　编辑：路艳华

Three dimensional (3D) heteroatom-doped active carbon as a flexible supercapacitor electrode is explored with a starting material of silkworm fibers and low molecular weight phenol resin composite. The silk fiber offers a 3D interconnected network and high content of oxygen and nitrogen functionalities, leading to a unique hierarchical structure and a high performance of the electrode. The combination of phenolic resin with silk fibers increases mechanical robustness and specific capacitance of the composite. The porous carbon composite electrode shows a high gravimetric specific capac
