Abstract

Polypyrrole and polythiophenes doped with redox-active Fe(CN)64− anions deliver a 56% to 300% enhanced redox capacity and also exhibit greatly improved cycling stability, enabling them to be used as a new class of low-cost, environmentally benign, and high-capacity cathode material for electric storage applications.
