Abstract

Pergeseran ke sumber energi yang lebih ramah lingkungan disebabkan oleh peningkatan emisi gas rumah kaca dan kerusakan lingkungan. Namun, problematika yang ada pada baterai mendorong untuk beralih ke sistem penyimpanan energi hybrid. Baterai yang memiliki energy density yang tinggi tetapi power density yang rendah, sementara superkapasitor menawarkan keunggulan dalam masa pakai, power density, dan kecepatan pengisian. Kombinasi baterai dan superkapasitor diharapkan dapat menggabungkan keunggulan keduanya dimana diharapkan bisa meningkatkan kapasitansi spesifik, power density, dan energy density. Penelitian ini menyintesis komposit Ni(OH)2/NiMoO4 pada template reduced graphene oxide/nickel foam sebagai pendekatan untuk meningkatkan performa sistem penyimpanan energi hybrid. Dimana rGO menjadi bagian superkapasitor dan NiMoO4 bagian baterai. Variasi penambahan massa Ni(NO3)2.6H2O (1.75, 2.125, dan 2.5 gr) digunakan untuk menganalisis pengaruhnya terhadap struktur dan morfologi komposit tersebut. Karakterisasi yang dilakukan meliputi XRD, FTIR, dan SEM-EDX untuk menganalisis struktur dan morfologi komposit. Sedangkan pengujian CV, EIS, dan GCD dilakukan untuk menganalisis nilai kapasitansi dan konduktivitas listrik dari komposit. Dari hasil pengujian karakterisasi disimpulkan komposit Ni(OH)2/NiMoO4/rGO/NF berhasil disintesis dengan komposisi 49.20wt% Ni, 30.05wt% Mo, dan C sebesar 01.52%. Kemudian pada pengujian elektrokimia, variasi penambahan massa Ni(NO3)2.6H2O dengan kapasitansi terbesar dan sifat kapasitif terbaik adalah pada variasi penambahan terkecil 1.75 gram dengan nilai kapasitansi dari hasil uji CV sebesar 349.06 F/g dengan scan rate 5 mV/s, nilai konduktivitas dari hasil uji EIS sebesar 1.301 Sm-1, dan GCD sebesar 283.93 F/g pada current density 0,25 A/g.

The shift to greener energy sources is due to the increase in greenhouse gas emissions and environmental damage. However, the existing problems with batteries are driving the shift to hybrid energy storage systems. Batteries have high energy density but low power density, while supercapacitors offer advantages in lifetime, power density, and charging speed. The combination of batteries and supercapacitors is expected to combine the advantages of both where it is expected to increase specific capacitance, power density, and energy density. This research synthesizes Ni(OH)2/NiMoO4 composite on reduced graphene oxide/nickel foam template as an approach to improve the performance of hybrid energy storage system. Where rGO becomes the supercapacitor part and NiMoO4 the battery part. Variations of Ni(NO3)2.6H2O mass addition (1.75, 2.125, and 2.5 g) were used to analyze its effect on the structure and morphology of the composite. Characterization includes XRD, FTIR, and SEM-EDX to analyze the structure and morphology of the composite. While CV, EIS, and GCD tests were carried out to analyze the capacitance and electrical conductivity values of the composites. From the characterization test results, it was concluded that the Ni(OH)2/NiMoO4/rGO/NF composite was successfully synthesized with a composition of 49.20wt% Ni, 30.05wt% Mo, and C of 01.52%. Then in electrochemical testing, the mass addition variation of Ni(NO3)2.6H2O with the largest capacitance and the best capacitive properties is the smallest addition variation of 1.75 grams with a capacitance value from the CV test results of 349.06 F/g with a scan rate of 5 mV/s, conductivity value from the EIS test results of 1,301 Sm-1, and GCD of 283.93 F/g at a current density of 0.25 A/g.
