H+ doped polyaniline nanofibre (PH) was synthesized by interfacial polymerization and polyanilines doped with Li salt (PLI and PHLI) were prepared by immersing emeraldine base (EB) and H+ doped polyaniline in 1 mol/L LiPF6/(EC-EMC-DMC),respectively.PH, PLI and PHLI were all characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectrometry.With 1 mol/L LiPF6/(EC-EMC-DMC) as electrolyte, PH , PHLI and PLI were used as the active materials of symmetric non-aqueous redox supercapacitors.PLI shows the highest initial specific capacitance of 120 F/g (47 F/g for PH and 66 F/g for PHLI) among three samples.After 500 cycles, the specific capacitance of PLI remains 75 F/g, indicating the good cycleability.
