Abstract: The active carbon was milled using self-made vibration mill.The influence of some kinds of binder,conductive agent,making technology of carbon electrode and different concentrations of electrolyte on the performance of carbon electrode was studied and the advanced program of making carbon electrode was determined.When the amount of agent of PTFE is 5％,the capacitance is the highest.The conductive agent of carbon black is the best to ameliorate the property of carbon electrode.The favorable technology of making electrode is as follows the desiccation temperature 100 ℃,electrode pressure 18 MPa;immersion hour 12 h and concentration of electrolyte 5 mol/L.
