In the present studies coconut shell based treated activated charcoal (CST) was synthesized by chemical activation method using KOH (potassium hydroxide) as an activating agent. Surface area analysis shows that CST has mesopores of size 3 nm having specific surface area of 1640 m(2) g(-1). Electrochemical double layer capacitor (EDLC) was fabricated using CST as an electrode material with blend polymer electrolyte having specific capacitance of 534 mF cm(-2) (equivalent to single electrode specific capacitance of 356.2 F g(-1)). The corresponding energy and power density of 88.8 Wh kg(-1) and 1.63 kW kg(-1), respectively, were achieved for EDLC. (C) 2013 Elsevier B.V. All rights reserved.
