Kinerja Grafit/N-Grafena dan Grafena/N-Grafena sebagai Katoda Sel Baterai Primer

Abstract

Research about the performance of Graphite/N-Graphene and Graphene/NGraphene as a cathode of primary battery cell was carried out. The purpose of this research is to know the performance of Graphite/N-Graphene and Graphene/NGraphene as a cathode of primary battery cell. This research used Hummers, dopan nitrogen and impregnation methods to synthesis Graphene, N-Graphene and generating of Graphite/N-Graphene and Graphene/N-Graphene, respectively. The XRD data show that there is a shifting in position of the diffraction peaks (Graphene at 2θ = 26,52º and N-Graphene at 2θ = 26,16º), meaning there are interactions of nitrogen and carbon atoms. The presence of N atoms on N-Graphene is also confirmed by EDX data, there is 2,72 % atoms, and peak at wave number 1396 cm-1 (FTIR data) shows the interaction between C and N. The conductivity data showed that graphene (858,21 μS/cm), N-Graphene (1157,32 μS/cm), Graphite/N-Graphene (1:2) (350,2 0μS/cm) and Graphene/N-Graphene (1:2) (969,33 μS/cm) are higher than the cathode’s primary battery (80,98 μS/cm). All data prove that N-Graphene, Graphite/N-Graphene and Graphene/N-Graphene have better performance than the cathode’s primary battery.

Penelitian tentang kinerja Grafit/N-Grafena dan Grafena/N-Grafena sebagai katoda sel baterai primer telah dilakukan. Tujuan penelitian ini adalah untuk mengetahui kinerja Grafit/N-Grafena dan Grafena/N-Grafena sebagai katoda sel baterai primer. Penelitian ini masing-masing menggunakan metode Hummers, dopan nitrogen dan metode impregnasi untuk sintesis grafena, N-Grafena dan pembuatan material Grafit/N-Grafena dan Grafena/N-Grafena. Data XRD menunjukkan adanya perubahan posisi puncak difraksi (Grafena dengan 2θ = 26,52º dan N-Grafena 2θ = 26,16º), artinya terjadi interaksi atom-atom nitrogen dengan karbon. Adanya atomatom N pada N-Grafena ditunjukkan oleh data EDX, yaitu 2,72 % atom, dan puncak pada bilangan gelombang 1396 cm-1 (Data FTIR) menunjukkan adanya interaksi antara C-N. Data konduktivitas menunjukkan grafena (858,21 μS/cm), N-grafena (1157,32 μS/cm), grafit/N-grafena (1:2) (350,20 μS/cm) dan grafena/N-grafena (1:2) (969,33 μS/cm) memiliki konduktivitas lebih tinggi dibandingkan dengan katoda baterai primer (80,98 μS/cm). Data-data tersebut membuktikan bahwa N-grafena, Grafit/N-Grafena dan Grafena/N-Grafena memiliki kinerja yang lebih baik dari katoda baterai primer.
