Coconut is a kind of tropical fruits which can grow well in Indonesia. Coconut
coir fiber can be a potential activated carbon because coconut fiber contains
lignin which is quite high, namely 35% -45%. This study aims to see the effect of
physical activation temperature on the specific capacitance of activated carbon
electrodes from coconut coir biomass with NaOH used as an activating agent.
Activated carbon electrodes from coconut coir biomass for supercapacitor cells
have been made with variations in physical activation temperature of 750ºC,
800ºC, 850ºC and 900ºC for samples M-750, M-800, M-850, and M-900,
respectively. Single step pyrolysis carried out included carbonization in the N2
atmosphere at 600ºC and physical activation in the CO2 atmosphere. Density is
evaluated based on the reduced dimensional approach of activated carbon such
as mass, diameter, and thickness. Microcrystalline properties were analyzed by Xray
diffraction method and showed good amorphous properties of activated
carbon. Functional group analysis performed using FTIR showed that the
activated carbon in this study contained the functional groups O-H, C = O, C =
C, C-C, and C-H. From the results of the electrochemical characterization of the
carbon electrode using the cyclic voltammetry method, it was found that a high
specific capacitance in the M-750 sample was 96.85 F g-1 in 1 M H2SO4
electrolyte at a low scan speed of 1 mV s-1 with energy density and power
respectively. - 13.45 Wh kg-1 and 48.46 W kg-1, respectively.
Keywords: activated carbon,coconut husk fiber, electrode material,
supercapacitor.
