A SEPARATOR STRUCTURE AND REDOX FLOW BATTERY CONTAINING THE SEPARATOR MEMBRANE

摘要

The present invention relates to a separator structure for a redox flow battery having a porous polymer membrane attached to both sides of an ion exchange membrane, and a redox flow battery including the separator structure.;Such a membrane structure attaches a porous polymer membrane to both sides of the ion exchange membrane to improve mechanical strength, which is a weak point of a thin ion exchange membrane, and thus is applied to a redox flow battery, thereby reducing the pressure difference generated in the flow of electrolyte. In addition to reducing the direct impact on the ion exchange membrane, battery life and efficiency can be improved, as well as protection of the electrolyte separator that distinguishes the positive and negative electrodes without increasing the internal resistance of the cell and prevention of cell short circuits.;Redox flow battery, ion exchange membrane, separator, porous polymer membrane, housing cell
