Abstract: 

Conducting plastic electrodes have been developed and investigated for the vanadium redox flow battery. It was found that although air oxidation of the felt resulted in a slight decrease in electrical conductivity, a significant increase in activity of the felt was obtained with thermal treatment of the felt. Finally, the performance of a vanadium redox flow cell employing the carbon-polypropylene composite electrode was evaluated and voltage efficiencies as high as95% were achieved at a charge/discharge current density of 20mA.cm-2.
