In this study,aniline was used as the monomer,ammonium persulfate as the oxidizing agent,phytic acid as the dopant acid,and lignosulfonate were chemically polymerized to synthesize lignosulfonate/polyaniline(LS/PANI)electrode materials with the good electron-conducting ability and excellent capacitance.The LS/PANI electrode materials were analytically characterized by using Field Emission Scan-ning Electron Microscope(FESEM),Fourier-transform Infrared Spectrometry(FT-IR),and Brunauer-emmett-teller(BET).The electro-chemical properties of LS/PANI electrode materials were tested by cyclic voltammetry,alternating current impedance,etc.The results showed that LS/PANI electrode materials as the electrode material had good capacitance performance and good cycling stability.Their specif-ic capacitance could reach 509.3 F/g at a current density of charge/discharge of 0.5 A/g,and the capacitance could be retained by 63.23％after cycling for 5 000 times at a charge/discharge current density of 10 A/g.
