Preparation of Acid-doped PANI Electrode Materials and Its Electrochemical Properties
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.
