A wide variety of transition metal oxides have long been at the center of the research of pseudocapacitor electrodes. NiO has in particular received great interest as one of the promising electrode materials for pseudocapacitors because of its high theoretical specific capacitance, excellent chemical and thermal stability, and low cost . However, NiO often suffers from low electrical conductivity and poor long-term durability. To address these hurdles, conductive additives such as activated carbon, carbon nanotubes, or graphene have been used. However, the use of a binder and non-homogeneous mixing with the carbon additives hinders the full utilization of NiO. In this work, we synthesized porous NiO nanotubes array on carbon fiber paper via a simple template method. The unique nanostructure of our NiO electrode led to the increase in contact area between electrolyte and electrode material, facilitated ion transport, and relieved strain induced during charge/discharge cycling. As a result, the NiO nanotubes integrated on carbon fiber paper exhibited a superior performance and long-term stability.
