Properties of electrochemically synthesized polymer electrodes Part VII: Kinetics of poly-3-methylthiophene in lithium cells

The electrochemical behaviour of poly-3-methylthiophene is discussed in comparison with that of other parent polymer electrodes, such as polythiophene and polydithiophene, on the basis of voltammetric and impedance response analysis. The results indicate that the kinetics of the redox processes of the three electrodes are controlled by ion diffusion into the polymer structure and that poly-3-methylthiophene is the most suitable material for the use as cathode in lithium, rechargeable batteries.
