Title:
ION-EXCHANGE MEMBRANE, METHOD FOR MANUFACTURING SAME, AND ENERGY STORING DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/171285
Kind Code:
A3
Abstract:
The present invention relates to an ion-exchange membrane, a method for manufacturing the same, and an energy storing device comprising the same. The ion-exchange membrane comprises: a porous support body comprising multiple pores; an ionic conductor filling the pores of the porous support body; and a silica coating layer that is positioned on the surface of the porous support body and comprises silica and an ionic conductor. An ion-exchange membrane according to an embodiment of the present invention has an improved bondability at an interface with other materials, which are bonded to the ion-exchange membrane, by means of surface energy control. Therefore, the ion-exchange membrane has a long-term durability maintained stably and thus can improve bonding durability not only when applied to an energy storing device, but also when applied to a power generating system. In addition, an ion-exchange membrane according to an embodiment of the present invention has a reduced resistance at an interface with other materials by means of surface energy control, and the through-plane exchange performance of the ion-exchange membrane is accordingly improved, making it possible to improve not only the bonding durability, but also the system efficiency.
