|1. (WO2018182191) ION EXCHANGE MEMBRANE, MANUFACTURING METHOD THEREFOR, AND ENERGY STORAGE DEVICE COMPRISING SAME|
|Applicants:||KOLON INDUSTRIES, INC
|Title:||ION EXCHANGE MEMBRANE, MANUFACTURING METHOD THEREFOR, AND ENERGY STORAGE DEVICE COMPRISING SAME|
The present invention relates to an ion exchange membrane, a manufacturing method therefor, and an energy storage device comprising the same. The ion exchange membrane comprises: a porous support including a plurality of pores; and an ion conductor filling the pores of the porous support, wherein the porous support includes a micropore having a size of 31 to 1000 μm. In addition, the ion exchange membrane has high charge/discharge cycle durability, high ion conductivity, and excellent chemical and thermal stability, and thus can achieve a high energy efficiency when applied to an energy storage device, such as a vanadium redox flow cell.
