| dc.description.abstract | Preparation of palm empty fruit bunch cellulose nanostructures as supercapacitor
electrodes based on Nickel Oxide and Graphene Oxide has been carried out. In this
study, characterization was carried out, among others: morphology test with
Scanning Electron Microscope (SEM), nanofiber size with Particle Size Analyzer
(PSA) test, to determine the functional groups (FT-IR), and electrochemical tests
using Cyclic Voltametry (CV) and Galvanostatic charge discharge (GCD). Cellulose
nanofibers from TKKS have been successfully isolated by ultrasonification method
and tested by particle size analyzer (PSA) test and obtained the size of TKKS
cellulose nanofibers 144 nm. In this study, 3ml of cellulose nanofibers, 60 mg of
graphene oxide (GO) were used with variations in the composition of nickel oxide 30
mg, 60 mg, and 90 mg stirred for 1 hour at 300 rpm until homogeneous then spread
on aluminum foil then dried in the oven. The highest specific capacitance value is
0.861 F/g with an area of 0.000917 cm2. The addition of nickel oxide affects the
specific capacitance value of the supercapacitor electrode. Then the highest energy
density value of 1.80 Wh/kg and the highest power density value of 28.173 W/kg
found in the NSSNiO90 sample. This shows the NSSNiO90 sample as the best
composition as a material for making supercapacitor electrodes. | en_US |
