Method for preparing ion conductivity membrane for flow battery through electrostatic spinning

The invention belongs to the technical field of electrochemical engineering and relates to a method for preparing an ion conductivity membrane for a flow battery through electrostatic spinning. In a high-voltage electric field, a carbon nanotube-doped non-fluorinated cation exchange polymer is dispersed into a spinning solution of an N,N-dimethyl formamide or N,N-dimethyl acetamide solvent; the spinning solution forms electrospun nanofiber on a receiving plate through the electrostatic force traction of a spinning nozzle to obtain the electrospun nanofiber with a three-dimensional network structure; and then solvent steam bath, hot pressing and protonation are carried out to prepare a compact membrane with ionic conductivity for the flow battery. Ions are conducted along the axial direction of the fiber to form a long-range ordered conducting channel; penetration of vanadium ions through a hydrophilic channel is significantly reduced through excellent ion barrier property of a carbon nanotube; and the electrospun membrane has relatively high mechanical strength and swelling resistance through fibration, therefore, the membrane disclosed by the invention obtains relatively high charge-discharge property of an all-vanadium flow battery.
