Sifat Fisis Dan Elektrokimia Elektroda Karbon Superkapasitor Berbasis Tempuru…

Carbon electrodes from coconut shell have been synthesized by addition of anionik surfactant of Sodium Dodecyl Sulfate (SDS) 1,5 M in the ball milling process. A chemical activation was performed by activator KOH for mass ratio of carbon and KOH was 1:4. Supercapacitor cells was fabricated by the spraying method on scrap paper as separator in the pressure of 8 kg/cm3. The spraying process was d…
