摘要： A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

摘要： Disclosed are a micropore-filled amphoteric membrane for low vanadium ion permeability, a method of manufacturing the same, and a vanadium redox flow battery including the amphoteric membrane. The micropore-filled amphoteric membrane for low vanadium ion permeability minimizes crossover of vanadium ions, which occurs between a catholyte and an anolyte in a redox flow battery, and has low membrane resistance and thus has remarkably improved performance as compared to commercially available ion-exchange membranes such as Nafion, and accordingly, can be effectively used in the manufacture of a redox flow battery. In addition, the micropore-filled amphoteric membrane is continuously manufactured through a roll-to-roll process, and thus the manufacturing process is simple and manufacturing costs can be greatly reduced.
