ABSTRACT
Paper-like electrodes are emerging as a new category of advanced electrodes for flexible supercapacitors (SCs). Graphene, a promising two-dimensional material with high conductivity, can be easily processed into papers. Here, we report a rational design of flexible architecture with Co9 S8 nanotube arrays (NAs) grown onto graphene paper (GP) via a facile two-step hydrothermal method. When employed as flexible free-standing electrode for SCs, the proposed architectured Co9 S8 /GPs exhibits superior electrochemical performance with ultrahigh capacitance and outstanding rate capability (469â
F g-1 at 10â
A g-1 ). These results demonstrate that the new nanostructured Co9 S8 /GPs can be potentially applied in high performance flexible supercapacitors.
