Mesophase pitch carbon fiber electrodes have been developed by melt spinning and subsequent carbonization process. The structure, composition, and electrochemical properties of the carbon fiber as an electrode material for vanadium redox flow batteries (VRFBs) have been characterized. The electrode has a higher porosity structure than conventional carbon paper. It is found that the oxygen functional groups on the electrode surface were lost due to carbonization, and subsequent activation may restore the oxygen functional groups. Cyclic voltammetry measurements have showed that the activity is not sufficient, but further activation has suggested that the activity can be improved.
