Abstract

We recently described the properties of a rechargeable battery fabricated from polypyrrole (pPY) doped with redox-active molecules. An interesting feature of this battery is that it performs better than electric double-layer capacitors (EDLC) at high-power densities. A polypyrrole-based cathode, however, becomes unstable after several charging and discharging cycles. Based on previous work by others, this instability during charging is most likely due to the overoxidation of pPy at potentials above 700mV vs. Ag/AgCl. To overcome issues associated with the overoxidation of pPy, we replaced the pPy cathode with poly-3,4-ethylenedioxythiophene (PEDOT). In this talk, the PEDOT-based cathode will be described including detailed spectroscopic and electrochemical analysis of the films and batteries fabricated with this material.
