| dc.description.abstract | Research on the performance analysis of various of mass ratio on Iron/Graphene Nano Sheets (GNS)//Electrolyte//GNS as primary battery electrodes has been carried out. The purpose of this study was to produce Fe/GBN/NH4Cl-MnO2/GBN primary battery electrodes using the alloy method with variations in mass ratios 1 : 1 : 2, 1 : 2 : 1, 2 : 1 : 1, 2 : 2 : 1, and 2 : 1 : 2. To evaluate the performance of Fe/GBN/NH4Cl-MnO2/GBN primary battery electrodes with a mass ratio of 1 : 1 : 2, 1 : 2 : 1, 2 : 1 : 1, 2 : 2 : 1, and 2 : 1 : 2.This research is an experimental laboratory research and descriptive. GNS was produced from coconut shell as a raw material by using pyrolysis method, Fe/GBN anode was synthesized by impregnation method, and preparation of Fe/GNS//Electrolyte/GNS electrodes under various of weight ratio using alloy method. Analysis on GNS, Fe/GNS anode, and Fe/GNS//Electrolite/GNS electrodes were carried out with X–Ray Diffraction (XRD), Scanning Electron Microscope–Energy Dispersive X–Ray (SEM–EDX) and Multimeter, respectively. The research results show there is a weak and broad peak at 2θ = 24.62° of the GNS, this proves that GNS is successfully synthesized. This data is well confirmed by using SEM–EDX data too. The diffraction patterns of Fe/GNS anode and Fe/GNS//Electrolyte//GNS with variations in weight ratio show there is a weak and sharp peak at 2θ = 45° proving that Fe has been well deposited onto GNS. The existance and the quantity of Fe atoms in GNS surfaces may be proved with SEM-EDX data. The electrode of Fe/GNS//Electrolite//GNS with mass ratio 2 : 1 : 2 has the highest conductivity numbers (562,80 μS/cm2), power density (128,15 W.kg-1) and energy density (20,52 Wh.kg-1) among the others of electrodes. All of the research data show that the performance of primary battery electrodes may be increased with the exactly of mass ratio numbers of electrodes (Anode//Electrolite//Cathode), the type and composition of materials which are used as electrode and also the chemical interaction occur between Fe/GNS//Electrolite//GNS. | en_US |
