Performance of N-Doped Graphene Nano Sheets on Electrode of Primary Battery Cells

Abstract

Abstract Research on performance of N-Doped Graphene Nano Sheets (N-G) from coconut fruits as well as raw materials was carried out. The aims of this research are to produce gram scale N-G and evaluate its performance act as an electrode of primary battery cells. In this research, Graphene Nano Sheets (GNS) was produced from coconut fruits by using pyrolysis method. Then, N-G was generated with N-doped method where ammonia solution and room temperature were used as N atoms source and temperature doping, respectively. Finally, N-G was characterized with XRD, SEM-EDX, TEM, XPS, Raman and conductometer. XRD data shows that C (002) peak of N-G shifts to higher 2θ number comparing to GNS that is N-G (2θ = 24,72o) and GNS (2θ = 23.86o), indicating there is interaction between carbon and nitrogen on N-G. This data is consistent with XPS data namely the type of N-G is N-pyridin (BE = 402.0 eV) and C-N (BE = 286.8 eV). Interestingly, the TEM images show clearly N-G has the flat surface and the graphene layers distance are little bit expanding (0.36 nm) compare to graphene layers (0.34 nm). SEM images and EDX data also may prove the morphology structure like the honey comb lattices and containing N atoms dominant. Raman data succeed to clarify D-band and G-band from N-G. All of data show that N-G is well produced and proved. In addition, the good findings N-G has electrical conductivity and it may be used as an electrode on primary battery cells.
