Embodiment approach

[0057] Hereinafter, embodiments of the present invention will be described in detail so as to be easily implemented by those skilled in the art. However, the present invention may be embodied in various different forms and is not limited to the exemplary embodiments described herein.

[0058] An ion exchange membrane according to an embodiment of the present invention includes a porous support having a plurality of pores, and an ion conductor filled in the pores of the porous support, wherein the porous support includes micropores.

[0059] The porous support may be a nonwoven fibrous web formed from randomly oriented plurality of fibers.

[0060] Nonwoven webs are interlaid, but refer to sheets with a single fiber or filament structure, not in the same way as fabrics. Nonwoven webs can be prepared by wet-laid processes such as those described below.

[0061] The basic weight of the nonwoven web may be 5 g / m 2 to 30g / m 2 . If the basis weight of the nonwoven web is less t...

experiment example

[0204] [Experimental example: Measurement of the properties of the prepared ion exchange membrane]

[0205] For the ion exchange membranes in the form of reinforced composite membranes prepared in Preparation Example 3 (Preparation Example 1) and Comparative Preparation Example 1 to Comparative Preparation Example 3 (Comparative Example 1 to Comparative Example 3), the swelling in the energy storage system (VRFB) was measured ratio, ionic conductivity and energy efficiency (EE), and the results are shown in Table 1.

[0206] The thickness and area of ​​the ion-exchange membrane were measured by immersing the prepared ion-exchange membrane in distilled water at 80°C for 24 hours and taking out the wetted ion-exchange membrane, and after drying the ion-exchange membrane at 80°C for 24 hours, the ion-exchange membrane was measured. The thickness and area of ​​the membrane, and then the thickness T in the wet state of the ion-exchange membrane wet and area L wet and the thicknes...
