Preparation of Activated Carbon by KOH Activation from Amygdalus Pedunculata Shell and its Application for Electric Double-layer Capacitor

Abstract

Activated carbon was prepared from Amygdalus pedunculata shell by carbonization and KOH activation. A. pedunculata is a good candidate plant for desert greening in China. By choosing the activation conditions, the activated carbon with the microporous structure and the large surface area (2900m2 g-1) was obtained. The resulting activated carbon exhibited the good electrochemical capacitive behavior. The present activated carbon from A. pedunculata is a promising electrode material for high-performance electric double-layer capacitor.
