Abstract

Kombinasi dua sifat energy storage yakni baterai dan superkapasitor menjadi perangkat baterai superkapasitor hibrida adalah kunci utama dalam mengatasi keterbatasan baterai pada kendaraan listrik. Sintesis material elektroda Ni(OH)2/CNT/rGO/NF yang menggabungkan sifat – sifat unggulan dari Ni(OH)2 , CNT, dan rGO pada base template Nickel Foam dengan metode hidrotermal diharapkan dapat menjadi kombinasi yang efektif untuk meningkatkan kinerja elektrokimia dari baterai superkapasitor hibrida. Sintesis dilakukan dengan variasi penambahan massa Ni(NO3)2.6H2O sebesar 1,375 gr; 1,75 gr; 2,125 gr untuk mengetahui pengaruhnya terhadp struktur dan morfologi serta kinerja elektrokimia dalam aplikasi baterai superkapasitor hibrida. Pengujian karakterisasi yang dilakukan meliputi SEM-EDX, XRD, FTIR untuk mengetahui struktur dan morfologi dari komposit. Hasil EDX menunjukkan komposit telah berhasil disisntesis dengan adanya kandungan unsur C 67.50 wt%, O 17.47 wt%, dan Ni 15.03 wt%. Penambahan massa Ni(NO3)2.6H2O dalam Ni(OH)2/CNT/rGO/NF tidak merubah struktur dan morfologi dari komposit. Hal ini dibuktikan dengan hasil pengujian XRD dan FTIR. Namun, pengujian SEM mengonfirmasi adanya persebaran Ni(OH)2 yang tidak merata pada variasi terbesar yakni penambahan 2.125 gram Ni(NO3)2.6H2O pada komposit Ni(OH)2/ CNT/rGO/NF. Performa elektrokimia dari komposit Ni(OH)2/CNT/rGO/NF dievaluasi melalui pengujian CV, EIS, dan GCD. Dari ketiga pengujian tersebut didapatkan variasi penambahan 1.75 gram Ni(NO3)2.6H2O pada komposit Ni(OH)2/ CNT/rGO/NF memiliki performa elektrokimia yang paling optimal dengan nilai kapasitansi spesifik sebesar 141.07 F/g, Energy Density sebesar 44.08 Wh/Kg dan Power Density sebesar 467.53 W/Kg dari hasil pengujian CV pada scan rate 5 mV/s, konduktivitas sebesar 1.134 S/m dari hasil pengujian EIS, dan nilai kapasitansi spesifik sebesar 129.2 F/g dengan waktu discharge 129.2 pada kerapatan arus 0.5 A/g.

The combination of two energy storage properties, namely battery and supercapacitors into a hybrid supercapacitor battery device is the key to overcoming the limitations of batteries in electric vehicles. Synthesis of Ni(OH)2/CNT/rGO/NF electrode materials which combines the excellent properties of Ni(OH)2, CNT, and rGO on Nickel Foam base template with hydrothermal method is expected to be an effective combination to improve the electrochemical performance of electric vehicles battery. The synthesis was carried out with variations in the mass addition of Ni(NO3)2.6H2O of 1.375 g; 1.75 g; 2.125 g to determine its effect on the structure and morphology as well as the electrochemical performance of the hybrid supercapacitor battery applications. Characterization tests carried out include SEM-EDX, XRD, FTIR to determine the structure and morphology of the composite. EDX results results show that the composite has been successfully synthesized with the presence of the elements C 67.50 wt%,O 17.47 wt%, and Ni 15.03 wt%. Mass addition of Ni(NO3)2.6H2O in Ni(OH)2/CNT/rGO/NF did not change the structure and morphology of the composite. This is evidenced by the XRD and FTIR test results. However, the SEM testing confirmed the uneven distribution of Ni(OH)2 in the largest variation, namely the addition of 2.125 grams of Ni(OH)2/CNT/rGO/NF composite. Electrochemical performance of Ni(OH)2/CNT/rGO/NF composite was evaluated through CV, EIS, and GCD. From the three tests obtained the variation of adding 1.75 gram of Ni(NO3)2.6H2O to the Ni(OH)2/CNT/rGO/NF composite has the most optimal electrochemical performance with a capacitance value of 141.07 F/g, Energy Density of 44.08 Wh/Kg and Power Density of 467.53 W/Kg from the CV test results at a scan rate of 5 mV/s, conductivity of 1.134 S/m from the results of the EIS testing, and a specific capacitance value of 129.2 F/g with a discharge time of 129.2 s at a current density of 0.5 A/g.
