Title: Electrochemical redox properties of polypyrrole/Nafion composite film in a solid polymer electrolyte battery

Abstract

Nafion{reg_sign} was introduced into a polypyrrole (PPy) matrix, and the redox performance of the PPy/Nafion electrode was investigated in a polyethylene oxide (PEO)-LiClO{sub 4} electrolyte. A rougher interface between polymer cathode and polymer electrolyte is usually needed for an all-solid battery, however, the PPy/Nafion cathode works well regardless of the flat surface of the PPy/Nafion film. When compared to a PPy film doped with ClO{sub 4}{sup {minus}} anions with a similar morphology, the PPy/Nafion film showed better redox performance. The results of the impedance spectroscopy and potential-step chronoamperometry confirmed that the improvement in the redox reaction of the PPy/Nafion film was due to the enhancement of the ion diffusion rate in the film. Thus, the PPy/Nafion film showed good charging-discharging properties in a rechargeable Li/PEO-LiClO{sub 4}/(PPy/Nafion) battery.
