Analisis Variasi Rasio Massa Elektrolit NH4Cl, Anoda Cu/Grafena Berlapis Nano dan Katoda Grafena Berlapis Nano pada Prototipe Baterai Primer

Abstract

Research on Analysis of Variation of Mass Ratio of NH4Cl Electrolyte, Cu/Graphene Nano Sheets Anode and Graphene Nano Sheets Cathode on Primary Battery Prototype was carried out. The aims of this research are to analyze gram scale of Graphene Nano Sheets (GNS) production base on coconut shell as a raw material and to analyze performance of our prototype of primary battery (fuse battery) namely Cu/GNS//NH4Cl//GNS with mass weight ratio 1 : 2 : 1 and 2 : 1 : 2. GNS, Cu/GNs and Cu/GNS//NH4Cl//GNS were produced by using composite methods, respectively. GNS was analzed with X-Ray Diffraction (XRD), Scanning Electron Microscope – Energy Dispersive X - Ray (SEM – EDX) and Multimeter. While, Cu/GNS (without electrolyte) and Cu/GNS//NH4Cl//GNS, we analyzed the conductivity values with Multimeter. The XRD data show there is a weak and broad peak of C (002) at 2θ = 24,32o, proving GNS may be well synthesized. This XRD data is consistent with SEM-EDX where the thin layer of GNS may be seen. The conductivity data of Cu/GNS//NH4Cl//GNS with mass weight ratio 1 : 2 : 1 has the highest conductivity values (879.66 μS/cm2 ), power density (180.75 W.Kg-1), energy density (612.08 Wh.Kg-1) compare to 2 : 1 : 2. The all of data show the performance of primary battery may be improve by using mass weight ratio of Anode//Eletrolyte//Cathode, the type of material and the chemical interactions that occur at the Anode//Eletrolyte//Cathode.
