The　novel　IrO2-CeO2-G/Ti　composite　electrodes　were　prepared　by　thermal　decomposition　method.　The　synthesized　electrodes　with　different　IrO2　content　were　characterized　by　scanning　electron　microscope　(SEM),　transmission　electron　microscope　(TEM),　X-ray　diffraction　(XRD)　and　X-ray　photoelectron　spectroscopy　(XPS).　The　electrochemical　performances　of　the　electrodes　were　investigated　by　cyclic　voltammetry,　galvanostatic　charge-discharge　and　electrochemical　impedance　spectroscopy　in　0.5　mol/L　H2SO4　solution.　The　results　show　that　the　electrode　with　2.5　mg/cm2　IrO2　exhibits　an　excellent　specific　capacitance　value　of　459.5　F/g,　and　maintains　the　specific　capacitance　at　about　97.8%　after　5000　charge-discharge　cycles　at　5　mA/cm2　current　density.　The　electrode　with　2.5　mg/cm2　IrO2　is　an　ideal　electrode　for　supercapacitor　due　to　its　unique　composition　proportion　and　the　excellent　pseudocapacitance　property.　Copyright　©　2020,　Northwest　Institute　for　Nonferrous　Metal　Research.　Published　by　Science　Press.　All　rights　reserved.
