Efekvariasi Waktu Ball Milling Terhadap Karakteristik Elektrokimia Sel Superkapasitor Berbasis Karbon

---

Supercapacitor electrodes from rubber wood saw dust (RWSD) have been
fabricated using experiment method with ball milling time variation of 20, 40,
and 80 hours and thickness of 0.2 mm. Carbon electrodes were carbonized at
600oC an followed by physical activation method in CO2 gas atmosphere on the
constant temperature of 900oC, and chemical activation was performed by KOH
as an activating agent. Densities of the electrodes were 0.849 g/cm3, 0.892 g/cm3,
and 0.982 g/cm3 respectively. XRD measurement showed the peaks of carbon
electrodes at 2θ of 24.079o and 44.473o which represented the presence of carbon
materials with their crystal orientation of (002) and (100). SEM micrograph on
magnification of 1000 and 5000X showed that the pore distribution of the carbon
electrodes dominant on macropores. This study found that the effects of
increasing of ball milling time influenced the electrochemical properties of
supercapacitor electrodes from RWSD. The optimum supercapacitor performance
was found on 20 hours milling time electrode and had a specific capacitance of
55.414 F/g.
