Karbon Aktif Berbasis Daun Manggis (Garcinia Mangostana) Dengan Penambahan Karbon Nanotube Untuk Elektroda Sel Superkapasitor

---

Supercapacitor performance is influenced by pore size and pore distribution on the electrode surface, high thermal conductivity and electrolyte ion size to achieve high specific capacitance values. Electrodes were synthesized from mangosteen (garcinia mangostana) leaf biomass through pre-carbonization, chemical activation, carbonization and physical activation processes. The samples were activated with KOH activator and the addition of 5% and 10% carbon nanotubes with sample codes DM, DMN-5 and DMN-10, respectively. The largest percentage of density shrinkage is owned by the DMN-5 sample which is 27.484%. The DMN-5 sample has an electrode microstructure with a semicrystalline structure. The mesoporous and nanofiber structures are owned by the DMN-5 sample with a carbon percentage element of 95.0%. The surface area of DMN-5 sample in BET analysis is 429.20 m2/g with C-H, C=O and C-O functional groups which have good conductivity characteristics. Electrochemical analysis of supercapacitor cells using Cyclic Voltammetry method with 1 M H2SO4 shows DMN-5 has the highest specific capacitance value of 330.95 F/g. Based on the results of the physical and electrochemical properties of mangosteen leaf-based supercapacitor cells (garcinia mangostana) with the addition of carbon nanotubes in the carbon matrix can improve the performance of supercapacitor cells.
