Abstract

Fabrikasi elektroda hybrid baterai superkapasitor berbahan komposit Ni(OH)2/CNT/rGO/NF diharapkan mampu memberikan kinerja elektrokimia yang baik dari segi jenis hybrid baterai superkapasitor. Penelitian ini mensintesis komposit Ni(OH)2/CNT/rGO/NF sebagai pendekatan untuk meningkatkan performa sistem penyimpanan energi hybrid. Ni(OH)2 memiliki densitas daya dan kemampuan siklus yang baik. CNT memiliki luas permukaan yang luas dan berpori yang memudahkan transfer muatan dan konduktivitas listriknya baik. Dengan sifat dan karakteristik dari masing-masing material untuk perangkat hybrid baterai superkapasitor diharapkan dapat memberikan kinerja elektokimia, stabilitas siklus, dan transfer muatan yang baik dan efisien. Komposit Ni(OH)2/CNT ditumbuhkan dalam reduce graphene oxide/nickel foam melalui metode hidrotermal. Variasi penambahan massa CNT ( 6 mg, 8 mg, 10 mg) digunakan untuk menganalisis pengaruhnya terhadap struktur dan morfologi komposit tersebut. Karakterisasi yang dilakukan antara lain XRD, FTIR, dan SEM-EDX untuk menganalisis struktur dan morfologi. Sedangkan pengujian CV, EIS, dan GCD dilakukan untuk menganalisis nilai kapasitansi dan konduktivitas listrik dari komposit Ni(OH)2/CNT/rGO/NF. Dari hasil pengujian karakterisasi disimpulkan bahwa komposit Ni(OH)2/CNT/rGO/NF berhasil disintesis dengan komposisi 67.6%wt unsur C, 17.47% unsur O dan 15.03% unsur Ni. Penambahan massa CNT pada semua variasi komposit Ni(OH)2/CNT/rGO/NF berpengaruh terhadap kinerja elektrokimianya. Dimana pada variasi C3 (10 mg CNT) memiliki nilai kapasitansi yang paling tinggi dan sifat kapasitif yang baik berdasarkan hasil uji CV dengan kapasitansi sebesar 150,6 A/g pada scan rate 5 mV/s, untuk hasil pengujian EIS dengan nilai konduktivitas sebesar 2.03 S/m, dan hasil pengujian GCD sebesar 218,7 A/g. Sehingga pada komposit Ni(OH)2/CNT/rGO/NF variasi penambahan massa CNT sebesar 10 mg memiliki performa elektrokimia paling optimal dibandingkan dengan komposit lainnya.

The fabrication of hybrid electrode of supercapacitor battery made from Ni(OH)2/CNT/rGO/NF composite is expected to provide good electrochemical performance in terms of hybrid type of supercapacitor battery. This research synthesizes Ni(OH)2/CNT/rGO/NF composite as an approach to improve the performance of hybrid energy storage system. Ni(OH)2 has good power density and cycleability. CNTs have a large and porous surface area that facilitates charge transfer and good electrical conductivity. The properties and characteristics of each material for the hybrid supercapacitor battery device are expected to provide good and efficient electochemical performance, cycle stability, and charge transfer. Ni(OH)2/CNT composite was grown in reduced graphene oxide/nickel foam through hydrothermal method. Variation of CNT mass addition (6 mg, 8 mg, 10 mg) was used to analyze its effect on the structure and morphology of the composite. Characterizations performed include XRD, FTIR, and SEM-EDX to analyze the structure and morphology. Meanwhile, CV, EIS, and GCD tests were conducted to analyze the capacitance and electrical conductivity values of the Ni(OH)2/CNT/rGO/NF composite. From the characterization test results, it was concluded that the Ni(OH)2/CNT/rGO/NF composite was successfully synthesized with a composition of 67.6%wt C element, 17.47% O element and 15.03% Ni element. The addition of CNT mass in all variations of Ni(OH)2/CNT/rGO/NF composites affects the electrochemical performance. Where in variation C3 (10 mg CNT) has the highest capacitance value and good capacitive properties based on CV test results with a capacitance of 150.6 A/g at a scan rate of 5 mV/s, for EIS test results with a conductivity value of 2.03 S/m, and GCD test results amounting to 218.7 A/g. Thus, the Ni(OH)2/CNT/rGO/NF composite with 10 mg CNT mass addition variation has the most optimal electrochemical performance compared to other composites.
