Abstract

Graphene merupakan material yang memiliki kristal tersusun dari lembaran bidang karbon berbentuk heksagonal. Graphene dapat dimanfaatkan sebagai bahan pembuatan superkapasitor. Superkapasitor merupakan piranti yang dapat menyimpan energi dan memberi energi.. Graphene merupakan material yang sangat sesuai dan dapat diaplikasikan sebagai elektroda superkapasitor. Penelitian ini bertujuan untuk menganalisis pengaruh temperatur hidrotermal (190oC, 200oC, dan 210oC) terhadap sifat kapasitif superkapasitor berbahan graphene. Penelitian dimulai dengan mengoksidasi grafit menjadi grafit oksida dengan metode Hummer. Setelah grafit oksida disintesis maka dilanjutkan dengan mereduksi grafit oksida menjadi graphene. Karakterisasi material menggunakan X-Ray Diffraction (XRD), Scanning Electron Microschope (SEM). Menentukan konduktifitas menggunakan Four Point Probes (FPP). Menggunakan Cyclic Voltammetry (CV) untuk mementukan kapasitansi relatif elektroda dengan mendepositkan graphene ke dalam nickel foam dengan menggunakan elektrolit Na2SO4. ======================================================================================================================== Graphene is a material that has a crystal composed of hexagonal sheets of carbon field. Graphene can be used as materials for supercapacitors. Supercapacitor is a device that can store energy and provide energy. Graphene is a material that is very appropriate and applicable as supercapacitor electrodes. This study aimed to analyze the influence of hydrothermal temperatures (190oC, 200oC and 210oC) of the capacitive properties of graphenebased supercapacitors. The research begins by oxidizing graphite into graphite oxide with Hummer method. After the graphite oxide synthesized then followed by the reduction of graphite oxide to graphene. Material characterization using X-Ray Diffraction (XRD), Scanning Electron Microschope (SEM). Determining conductivity using the Four Point Probes (FPP). Using Cyclic voltammetry (CV) to determine relative capacitance electrode by depositing graphene into nickel foam using Na2SO4 electrolyte.
