Carbon Aerogel/Polyaniline Composite as Supercapacitors Packaging Applications

摘要：

　　Carbon aerogel (CA) /polyaniline (PANI) composite electrode materials was prepared by chemical oxidation polymerization through doped carbon aerogel with polyaniline.Themorphology and surface area of the composite have been investigated by scanning electron microscope and Brunaner–Emmett–Teller measurement,respectively.Electrochemical properties of the CA/PANI composite have been studied by cyclic voltammograms,galvanostatic charge/discharge,and electrochemical impedance spectroscopy measurements in 6 mol L-1KOH electrolyte.The results show that the CA/PANI composite is more uniformly distributed than CA and,moreover,CA/PANI composite has better electrochemical performance and high charge/discharge properties than CA.The results based on discharge current show that the composite material has a high specfiic capacitance of 126.15 F g-1,while the capacitance of CA electrode is 103.75 F g-1.The specific capacitance of CA/PANI was higher than CA after 100 cycles at a current of 10mA.
