In this paper, carbon felt was produced by carbonizing and graphitizing Oxi-PAN fiber (oxidized polyacrylonitrile fiber, stabilized fiber) nonwoven fabric. The physical, mechanical and electrical properties of the carbon felt produced in this way were compared with those of commercialized carbon fiber felt for conventional Redox Flow Battery. As the GSM of Oxi-PAN increased, the porosity and pore size decreased. The GSM after carbonization of the prepared Oxi-PAN felt sample was reduced by about 40%, but the differences according to the carbonization and graphitization temperature conditions showed little change in all the basic characteristics except electrical resistivity and tensile characteristics. The specific resistivity was reduced to $1.25{\Omega}{\cdot}mm$ at $2000^{\circ}C$ compared to about $2.05{\Omega}{\cdot}mm$ at $1000^{\circ}C$ based on the Oxi-PAN 900 GSM sample. Compared with commercial products, carbon felt made with Oxi-PAN 900 GSM is considered to be the best electrode.
