description: Herein, a one-step fabrication of three-dimensional (3D) binder-free graphene-nickel foam (G-Ni) electrode via  atmospheric pressure chemical vapour deposition (APCVD) is reported. Graphene thin films were deposited on nickel  foam under isobaric conditions in an inert environment. The process parameters such as temperature, time, and the gas  flow rate were statistically optimised using design of experiment (DOE) to maximise the yield of graphene. The  structural and morphological properties of the fabricated graphene electrode were investigated through X-ray diffraction  (XRD), Raman spectroscopy, field emission scanning electron microscopy (FESEM), and energy dispersive X-ray  spectroscopy (EDS). The electrochemical investigations were conducted through cyclic voltammetry (CV) and  View PDF  Download full issue  a a b b  c d e a  Share Cite  Optimising the fabrication of 3D binder-free graphene electrode for electrochemical energy storage application - ScienceDirect  file:///C|/Users/DELL/Documents/For%20upload/S0257897221002541.htm[26/10/2023 12:31:53]  electrochemical impedance spectroscopy (EIS) measurements. The results confirmed few-layered graphene with good  surface morphology, high purity, and crystallinity of a binder-free electrode. The statistical analysis revealed that the  optimal graphene electrode fabrication conditions were 900 °C, 10 min, and 100 sccm, respectively. Moreover, the  regressed model and experimental results for the graphene growth were determined to be 3.93 mg/cm , and  4.01 mg/cm , respectively. Electrochemically, a specific capacitance value of 62.07 F/g was recorded at a scan rate of  3 mV/s showing an excellent performance of the fabricated 3D graphene electrode for energy storage applications.
