The process parameter in optimized KOH alkali activation of soft carbon series coke material in high purity was setwith DOE experiments design. The activated carbon was produced by performing the activation process based onthe set process parameters. The specific surface area was measured and pore size was analyzed by N2 absorptionmethod for the produced activated carbon. The surface functional group was analyzed by Boehm method and metalimpurities were analyzed by XRF method. The specific surface area was increased over 2,000 m2/g as the mixingratio of activation agent increased. The micro pores in 5~15 A and surface functional group under 0.4 meq/g wereobtained. The contents of the metal impurity in activated carbon which is the factor for reducing the electrochemicalcharacteristics was reduced less than 100 ppm through the cleansing process optimization. The electrochemicalcharacteristics of activated carbon in 38.5 F/g and 26.6 F/cc were checked through the impedance measuring withcyclic voltammetry scan rate in 50~300 mV/s and frequency in 10 mHz ~100 kHz. The activated carbon was made inthe optimized activation process conditions of activation time in 40 minutes, mixing ratio of activation agent in 4.5 : 1.0and heat treatment temperature over 650℃.
