Abstract

Kebutuhan akan energi bertambah seiring dengan kemajuan teknologi sehingga diperlukan piranti penyimpanan energi yang berkapasitas besar dan efisien. Superkapasitor merupakan salah satu media yang memenuhi kriteria tersebut. Elektroda yang dapat digunakan pada superkapasitor yaitu grafena dengan sifat konduktivitas listrik dan luas permukaan yang besar. Untuk meningkatkan karakteristik dari grafena diberikan doping boron dan pengkompositan dengan CuCr2O4. Oleh karena itu, penelitan ini dilakukan dengan tujuan untuk menganalisis pengaruh komposisi komposit terhadap struktur, morfologi serta sifat kapasitif grafena yang didoping boron (B-doped rGO). Sintesis yang digunakan untuk pembuatan B-Doped rGO yaitu microwave assisted solvothermal, sedangkan pembuatan komposit menggunakan metode sol-gel. Variasi yang digunakan untuk pembuatan elektroda komposit B-Doped rGO:CuCr2O4 adalah 85:15; 90:10; dan 95:5. Analisis yang dilakukan menggunakan pengujian XRD, FTIR, SEM-EDX, dan CV. Didapatkan penurunan kadar CuCr2O4 dapat meningkatkan crystallite size sehingga kristalinitas komposit akan naik. Nilai kapasitansi tertinggi berturut-turut yang diperoleh oleh tiap komposit 85:15; 90:10; dan 95:15 adalah sebesar 84.3 F/g, 43.59 F/g, dan 36.06 F/g.

The need for energy increases in line with technological advances, so that large-capacity and efficient energy storage devices are needed. Supercapacitor is one medium that meets these criteria. The electrode that can be used in supercapacitors is graphene with electrical conductivity and large surface area. To improve the characteristics of graphene, boron doping was applied and composites with CuCr2O4 were applied. Therefore, this study was conducted with the aim of analyzing the effect of composite composition on the structure, morphology and capacitive properties of boron-doped graphene (B-doped rGO). The synthesis used for the manufacture of B-Doped rGO was microwave assisted solvothermal, while the composite was made using the sol-gel method. The variations used for the manufacture of B-Doped rGO:CuCr2O4 composite electrodes were 85:15; 90:10; and 95:5. The analysis was carried out using XRD, FTIR, SEM-EDX, and CV tests. It was found that a decrease in CuCr2O4 content can increase the crystallite size so that the crystallinity of the composite will increase. The highest capacitance values were obtained by each composite respectively 85:15; 90:10; and 95:15 are 84.3 F/g, 43.59 F/g, and 36.06 F/g.
