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.展开更多

In this paper, we have developed the material of electric double layer capacitors prepared from pyrolytic treatment of phenol formaldehyde resin. The experiment results of its electrochemical properties show that this kind of capacitor has a large capacity, good cycle life and can be used in a large scale.展开更多
