Abstract

Kinerja superkapasitor dipengaruhi oleh beberapa hal salah satunya elektroda. Pada umumnya, elektroda tersusun dari bahan-bahan seperti carbon, metal oxide, metal sulfide, dan lain-lain. Material carbon memiliki kepadatan energi yang rendah serta konduktivitas yang tinggi. Sedangkan metal oxide dan metal sulfide memiliki kepadatan energi yang tinggi serta konduktivitas yang rendah. Untuk meningkatkan kinerja superkapasitor, material tersebut perlu dikompositkan dengan material lain seperti carbon nanotubes (CNT). Review ini membahas mengenai penambahan CNT terhadap komposit berbasis CNT seperti komposit CNT/metal oxide, CNT/metal sulfide, dan CNT/carbon. Untuk menganalisis struktur komposit dilakukan pengujian XRD, SEM, dan TEM. Sedangkan untuk menganalisis sifat kapasitifnya dilakukan pengujian CV, GCD, dan EIS. Penambahan CNT terhadap komposit mampu meningkatkan konduktivitas listrik. Selain itu, juga mampu meningkatkan nilai kapasitansi, power density, energy density, serta menurunkan nilai resistansi transfer muatan. Komposit berbasis CNT/metal oxide memiliki performa paling baik dengan nilai kapasitansi spesifik mencapai 1585 F.g-1, power density mencapai 20700 W.kg-1, energy density mencapai 344.8 Wh.kg-1, dan resistansi transfer muatan mencapai 0.046 Ω. ==================================================================================================== The performance of supercapacitor can be influenced by several things, one of which is the electrode. In general, electrodes are composed of materials such as carbon, metal oxide, metal sulfide, and others. Carbon material has a low energy density and high electrical conductivity. Meanwhile, metal oxide and metal sulfide have a high energy density and low conductivity. To improve the performance of supercapacitor, these materials need to be combined with other materials such as carbon nanotubes (CNT). This review discusses about the addition of CNTs to CNT-based composites such as CNT/metal oxide, CNT/metal sulfide, and CNT/carbon composites. To analyse the composite structure, XRD, SEM, and TEM tests were performed. Meanwhile, to analyse its capacitive properties, CV, GCD, and EIS tests were performed. The addition of CNT to the composite is able to increase the electrical conductivity. In addition, it is also able to increase the specific capacitance, power density, energy density, and decrease the charge transfer resistance value. CNT/metal oxide based composites have the best performance with specific capacitance values reaching 1585 F.g-1, power density reaching 20700 W.kg-1, energy density reaching 344.8 Wh.kg-1, and charge transfer resistance reaching 0.046 Ω.
