Electrodes Based on Se Anchored on NiCoP and Carbon Nanofibers for Flexible Energy Storage Devices

“…as well as conductive high-molecular-weight polymers (polyaniline, polypyrrole, polythiophene, etc.) is considered to be an effective approach compared to elemental doping. − In addition, a recent drive toward the development of 1D carbon nanofibers (CNFs) has attracted more attention for the fabrication of next-generation high-performance flexible SC devices because of their intrinsic advantages such as light weight, high surface area, and excellent mechanical/chemical stability. , Kalai Selvan et al have synthesized CNF-encapsulated NiCoP via an electrospin technique and extracted a specific capacitance of 333 Fg –1 in a three-electrode system. However, they used poly­(vinylidene difluoride) as a binder to fabricate the electrode, which hinders the active sites of the electrode material and thereby reduces the electrochemical performance.…”
