Abstract

Abstract: A new precusor of activated carbon material——sugar was pyrolyzed under many different conditions. Experiments were carried out to search for optimal pyrolyzing conditions. It was found that sugar should be carbonized at 700 ℃ and activated with potassium hydroxide at 800 ℃. The activated carbon prepared from pyrolytic treatment of sugar is therefore potential candidates as electrode material of electric double layer capacitor.

Key words: Sugar, Activated carbon, Electrode, Electric double-layer capacitors(EDLC)
