On the improved electrochemistry of hybrid conducting-redox polymer electrodes

Abstract The electrochemistry of poly(2,5-dihydroxyaniline) (PDHA), a novel hybrid molecular configuration with redox active sites and electrical charge conduction along the polymer chain, has been recently reported. The theoretical capacity of this material is estimated at 443 mAh g−1, with high po...
