Supercapacitors based on carbon fiber reinforced polymer (CFRPs) were studied and the influence of surface treatment mechanical electrochemical properties was explored. Electrodes prepared by deposition graphene nanoplatelets (GNPs) combined with different binders (PVDF PVA) onto a fabric. A significant decrease in Interlaminar Shear Strength (ILSS) is observed when comparing solid electrolyte to structural resin (around 50 %). Moreover, addition any binder promotes ILSS due lower interfacial 20 % compared GNP-coated condition). Electrochemical impedance spectroscopy (EIS) analysis proves that capacitor can be fitted an equivalent circuit consisting R-CPE series elements. An increase bulk resistance using (29.7 22.7 kΩ) GNP-only-coated (10.2 kΩ). For this reason, supercapacitor best one specific capacitance coulombic efficiency, calculated Galvanostatic charge-discharge (GCD), 5.2 mF/g, showing also high stability over time. Energy storage capability successfully demonstrated proof concept powering LED after short charge time device.

As a new type of energy storage device, supercapacitors have the advantages high-power densities, high safety factors, and low maintenance costs, so they attracted widespread attention among researchers. However, major problem with is that their densities are not enough, which limits application. Therefore, it crucial to expand application scenarios increase density as much possible without diminishing advantages. The classification working principles introduced in this paper. electrochemical properties pure NiS materials, composites carbon sulfide transition metal oxides for summarized. This paper may assist design electrode materials NiS-based supercapacitors.
