Molecular Batteries: Harnessing Fe(CN)63- Electroactivity in Hybrid Polyaniline-Hexacyanoferrate Electrodes

Hybrid materials useful as electrodes in plastic batteries are investigated by these authors. The electroactive species hexacyanoferrate (HCF) and the conducting organic polymer polyaniline (PAni) are combined to create hybrid materials that show promise as cathode materials in rechargeable lithium batteries. The chemical and electrochemical synthesis of PAni/HCF as well as the material's electrochemical properties are reported. It is demonstrated that this material has not only a high specific charge and efficiency but also good cyclability.
