Abstract

The invention discloses the application of a porous ion-conducting membrane supported by an organic skeleton copolymer in a liquid flow battery. This type of film is prepared by dissolving the soluble organic skeleton copolymer precursor A in the casting solution, coating it on the support, and undergoing phase inversion in a non-solvent containing the organic skeleton copolymer precursor B. The film is formed During the process, precursor A and precursor B in-situ generate organic framework copolymers in the film. The prepared porous ion conduction membrane containing the organic framework copolymer is processed, dried and pickled to prepare the porous ion conduction membrane supported by the organic framework copolymer. The designed and prepared porous ion-conducting membrane has good battery performance in the flow battery, especially the all-vanadium flow battery.
