【Abstract】 Polyaniline doped with quaternary ammonium tetrachlorometallate [C18H37N(CH3)3]2MCl4(M=Co,Ni,Mn,Cu) was carried out by cyclic voltammetry(CV).The surface morphology and the structures of composite electrodes were characterized by scanning electron microscopy(SEM),fourier transform infrared spectroscopy(FTIR) and X-ray diffraction(XRD).The electrochemical properties of electrodes and the capacitive behavior of the resulting capacitors were systematically studied using CV,electrochemicalimpedance spectroscopy(EIS) and constant current charge-discharge tests.The specific capacitance of PANI / C18C3 Cu electrode was 389.63F/g.Moreover the PANI/C18C3 Cu electrodes remained good stability over 30charge-discharge tests,and its retention rate was 96.10%.更多还原
