Abstract

Seiring dengan perkembangan zaman, kebutuhan terkait energi juga semakin meningkat. Munculnya kendaraan listrik dengan jenis hybrid maupun full listrik menjadi salah satu inovasi terbaru yang telah luas dipergunakan. Saat ini penelitian terbaru yang dilakukan yaitu pembuatan superkapasitor dengan jenis hybrid, dimana menggabungkan karakteristik antara Electric Double Layer Capacitor (EDLC) dengan material Nitrogen-doped rGO dan Carbon Nanotubes (CNT) serta karakteristik dari pseudocapacitor dengan material Bi2O3. Pada penelitian ini bertujuan untuk mensintesis elektroda superkapasitor hybrid menggunakan N- rGO dan CNT yang dikompositkan dengan Bi2O3 serta menganalisis penambahan massa CNT denganrasiomassaBi2O3 :N-rGO:CNTyaitusebesar(1:1:0,05),(1:1:0,10),dan(1:1: 0,15) terhadap morfologi, struktur, dan sifat kapasitif dari elektroda superkapasitor berbahan komposit Bi2O3/N-rGO/CNT. Karakterisasi dilakukan pada pengujian SEM-EDX, XRD, dan FTIR. Sedangkan untuk mengetahui nilai kapasitansi dan konduktivitas listrik dilakukan pada pengujian CV, EIS, dan GCD. Penambahan massa CNT pada semua variasi komposit menunjukkan bahwa CNT dapat meningkatkan nilai kapasitansi dengan nilai tertinggi pada variasi K03 (1 : 1 : 0,15) sebesar 134.576 F/g pada pengujian CV, lalu pada pengujian EIS didapatkan nilai kapasitansi sebesar 124.321 F/g dengan nilai konduktivitas sebesar 2.225 Sm- 1 pada frekuensi 0.01 Hz, dan yang terakhir yaitu pengujian GCD dengan nilai kapasitansi saat charging yaitu sebesar 1135.7 F/g dan pada saat discharging sebesar 1124.4 F/g pada current density 1 A/g.
====================================================================================================As the times evolve, the impact on energy related needs is also increasing. The emergence of electric vehicles, both hybrid and fully electric types, has become one of the latest innovations widely used. Currently, the newest research being conducted is the creation of hybrid supercapacitors, which combine the characteristics of Electric Double Layer Capacitors (EDLC) with Nitrogen-doped reduced Graphene Oxide (N-rGO) and Carbon Nanotubes (CNT) materials, as well as characteristics of pseudocapacitors with Bi2O3 material. This research aims to synthesize hybrid supercapacitor electrodes using N-rGO and CNT composited with Bi2O3 and to analyze the addition of CNT mass with mass ratios of Bi2O3 : N-rGO : CNT of (1 : 1 : 0.05), (1 : 1 : 0.10), and (1 : 1 : 0.15) on the morphology, structure, and capacitive properties of supercapacitor electrodes made from Bi2O3/N-rGO/CNT composite. Characterization was carried out using SEM-EDX, XRD, and FTIR testing. Meanwhile, to determine the capacitance value and electrical conductivity, CV, EIS, and GCD tests were performed. The addition of CNT mass in all composite variations showed that CNT can increase the capacitance value with the highest value in the K03 variation (1 : 1 : 0.15) of 134,576 F/g in CV testing, then in EIS testing, a capacitance value of 124,321 F/g was obtained with a conductivity value of 2,225 Sm-1 at a frequency of 0.01 Hz, and lastly, GCD testing with a capacitance value during charging of 1135.7 F/g and during discharging of 1124.4 F/g at a current density of 1 A/g.
