Paper Title:
Research of Activated Carbon for Supercapacitor Prepared by Organic Template Method
  Abstract

Activated carbon was fabricated by using phenolic resin as carbon source, PEG as organic template, KOH as activator. The samples were analyzed by N2 adsorption, scanning electron microscopy (SEM). Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical performance of the samples. The results showed that the specific surface area of the prepared sample (AC1) was 2469 m2/g, the pore size was mainly in the range of 1.0~4.0 nm. At a current density of 7.5 mA/cm2, a specific capacitance of 327F/g was achieved, the equivalent series resistance (ESR) was 0.8Ω. Supercapacitors based on the sample have low ESR and excellent power property. For comparison, commercial AC (AC2) was also studied.
