The AC impedance spectra of thin polypyrrole films were obtained at open circuit potentials from to V vs SCE. Two limiting cases are discussed for which simplified equivalent circuits are applicable.
At very positive potentials, the predominantly nonfaradaic AC impedance of polypyrrole is very similar to that observed previously for finite porous metallic : Reginald M. Penner, Charles R. Martin. Physically or chemically attaching an Fe III /Fe II redox couple to the backbone of a conducting polymer leads to stabilization of the charge/discharge characteristics and higher electrode capacities.
Composite cathodes made from LiFePO 4 particles bound to polypyrrole show enhanced electrode capacities and better rate capabilities, as shown in the figure.
