Abstract
Iron (Fe), nickel (Ni), and cobalt (Co) coated cellulose papers were synthesized via the electroless plating method, and their electrochemical properties were investigated for flexible supercapacitor applications. Three different concentrations of FeCoNi to distilled water on cellulose paper were prepared, and it affected morphology and crystal structure, resulting in different surface area, porosity, and impedance. The best performance obtained was specific capacitance of 75 ± 0.5 Fg-1 at 1 Ag-1, specific energy of 7 Whkg−1, and specific power of 400 Wkg-1 with capacitance retention of 88.2 % and coulombic efficiency of 83 % after 1000 cycles.
