Supercapacitor have attracted much attention due to its fast power supply,long cycle life,simple principle,etc.Supercapacitors are widely used in consumer electronics.Activated carbon is a typical material for electric double layer capacitor.Here,we study the electrochemical performance of an activated carbon(TF-B520)bulky paper electrode made by vacuum filtration method.Cyclic Voltammetry and Constant Current Charge/Discharge were used to test the electrode capacitance and the rate performance.The results showing that TF-B520 activated carbon balky paper electrodes have the highest capacitance of 120F/g at scan rate lmV/s and good capacitor behaviour at scan rate below 20mV/s and current density below 250mA/g.
