Discrete Coating of CNT on Carbon Fiber Surfaces and the Effect on Improving the Electrochemical Performance of VRFB Systems

Carbon fiber, as an electrode material, has been widely used in all-vanadium liquid flow batteries. In order to further reduce the size of storage system, it is imperative increase current density battery and achieve high conductivity large electrostatic capacitance. The graphitization material improvement specific surface area also greatly affect performance redox Therefore, this paper, carbon nanotubes (CNTs) with a small diameter were coated on VRFB system by dispersion method improve cell performance. surface-modified was verified Raman spectroscopy, XRD SEM observations charge/discharge experiments.
