The PEDGA/PAN-based carbon nanofiber was prepared by electrospinning the composite solution consisted of PEDGA and PAN polymer solution. The morphology of PAN/PFA blend carbon nanofiber was characterized by SEM, XRD, XPS, and the electrical conductivity of PEDGA/PAN-based carbon nanofiber was measured with 4-probe method, and their electrochemical properties was investigated with impedance analysis, charge-discharge test. The PEDGA/PAN-based carbon nanofiber showed a high electrical conductivity and electrochemical properties due to their excellent morphology and high electrical conductivity. The addition of PEDGA as precursor of graphene shows the improved coulomb efficiency and specific capacity than PAN-based carbon nanofiber. |
