Fabrikasi Elektroda Karbon Dari Cangkang Biji Karet (Hevea Brasilinensis) Dengan Aktivasi Fisika Untuk Aplikasi Sel Superkapasitor

---

Physical activation greatly effects the quality of carbon electrodes in a
supercapacitor cell. Carbon electrondes are the main components in a
supercapacitor cell. Carbon electrodes in this research were produced from rubber
seed shell biomass through some step process which are a pre-carbonization
process, ballmilling, chemical activation with KOH 0,5 M as activator, monolith
pellets printing using a hydraulic press and a pyrolysis process with the
carbonization-physics aktivation stages. Carbonization pyrolysis was carried out
at a nitrogen gas atmosphere at a temperature of 600 C and on hold at a
temperature of 339 C for 1 hours. Physical activation pyrolysis was carried out at
a carbon dioxide atmosphere with temperature variations at 650 C, 750 C and
850 C for samples labeled as CBK-650, CBK-750 and CBK-850 samples
respectively. The results show that the highest density shrink age was shown on
CBK-750 which is 0,303 g/cm3. Microstructure characterization using XRD show
that the carbon electrodes is amorphous with a peak at an angle of 2 around
24 and 44 which describes the (002) and (100) planes. Characterization of
electrochemical properties using the cyclic voltammetry (CV) method shown that
the highest specific capacitance founded in the CBK-750 sample, which is
198.344 F/g. Based on the data of this research, it can be concluded that the
temperature of 750°C is the optimum temperature at physical activation process
to produce quality carbon electrodes from rubber seed shell biomass.
