Abstract
Polypyrrole(PPy) was first synthesized by chemical oxidative polymerization. Then the assembling of cells was made by using PPy as anode and the lithium cathode. Its electrochemical properties were tested using galvanostatic system. The influences of DC conductivity of PPy anode on Li/PPy secondary batteries were mainly studied. The results showed when using high conductivity PPy as anode active material, the doping–undoping of the anions was easy and the discharge capacity of the cell was high, after fifty cycles the coulombic efficiency was 99.2%, the electrochemical stability and cycling property were still good. From condensed matter physics, the doping manner of conducting PPy was explained. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
