Abstract:
The upscaling of pre-carbonized wood biomass processes for supercapacitor
applications has been completed and tested. The modified furnace was used as an
instrument for pre-carbonizing Kulim wood crab biomass for 1,5 hours. Modified
furnaces were found to be more effective in terms of time, effort, power as well as
lower production costs. The carbon production went through several stages and is
activated using KOH activator with a ratio of 1:1. Physical analysis through XRD,
SEM-EDS, FTIR, and N2 Gas Absorption tests was carried out and followed by
electrochemical analysis i.e CV and GCD tests. The results of the physical test of
the activated carbon of Kulim wood crab through the XRD test confirmed the
amorphous nature of the carbon material which was characterized by a gentle
diffraction peak at an angle of 22,1° and 44,6°, SEM-EDS confirm that the most
element of carbon was a hierarchical microstructure with a size of 39-118 nm. ,
FTIR shows the presence of O-H, C≡C, C=O, and C-H functional groups. N2 Gas
Absorption test results provides a specific surface area of carbon of 1070,89 m2g-1.
The resulting carbon electrode was confirmed to have an amorphous structure and
to have a specific capacitance of 163 F/g tested using a duck egg shell membrane
separator.
