Pengaruh Penambahan Karbon Nanotube Terhadap Karbon Berbasis Kulit Udang Windu (Penaeus Monodon) Untuk Elektroda Sel Superkapasitor

---

Supercapacitors are the new generation of green energy storage device consisting of electrodes, electrolytes, current collectors and separator. Elektrodes are the main important components made from activated carbon that have porosity so make high conductivity and large surface area. This study utilized tiger shrimp shells with the addition of 1,6%, 3,3% and 5% carbon nanotube with respective sample codes, namely KUW-05, KUW-10 and KUW-15. The manufacture of carbon electrodes was carried out by several processes, namely pra-carbonization process, chemical activation with KOH activator and addition carbon nanotube, carbonization process using N2 gas at 600ᵒC and physical activation using CO2 gas at 800ᵒC. The highest density shrinkage value is owned by the KUW-10 sample, which is 23,92%. The KUW carbon electrode contains functional groups O-H, C-H, C=C, C≡C, and C-O and has a semicrystalline structure characterized by the presence of peak (002) and (100) at angles of 22°-24° dan 44°-45°. The nanofiber structure is owned by by the KUW-10 sample with a carbon element percentage of 44,91% . The BET analysis exhibits combined behavior of type I and IV with the H4 hystresis loop which shows the largest total specific surface area and total pore volume in KUW-10 of 486,285 m2/g dan 0,109 cc.g-1. Electrochemical analysis of supercapacitor cells using the Cyclic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte resulted in the highest specific capacitance values belonging to the KUW-10 sample of 319,76 F/g and 213,46 F/g respectively. Based on the physical and electrochemical properties of KUW biomass-based supercapacitor cells with the addition of carbon nanotube to the carbon matrix might improve the performance of the supercapacitor cell electrodes.
Keywords: Penaeus monodon, Carbon electrodes, Nanotube, Supercapacitors.
