Abstract
Porous carbon felt electrodes for a redox flow battery can be improved by suitably oxidizing the porous carbon felt or by oxidizing carbon particles impregnated into the porous carbon felt. The electrode resistance and voltage efficiency of cells comprising such electrodes can be substantially improved. The invention is particularly suitable for use in vanadium redox flow batteries.
Claims18
An electrode for a redox flow battery comprising:
- a sheet of porous carbon felt;
- carbon particles impregnated into the porous carbon felt;
- and
- ionomer impregnated into the porous carbon felt;
- characterized in that the carbon particles are oxidized such that they are wettable by water.
