Title:
イオン交換膜、この製造方法、及びこれを含むエネルギー貯蔵装置
Document Type and Number:
Japanese Patent JP6646759
Kind Code:
B2
Abstract:
The present invention relates to an ion exchanging membrane, a method for manufacturing the same, and an energy storage system comprising the same. The ion exchanging membrane includes a porous support including a plurality of pores, a first ion conducting material located on one surface of the porous support, and a second ion conducting material located on the other surface of the porous support, in which the first ion conducting material and the second ion conducting material are polymers including hydrophilic repeating units and hydrophobic repeating units, and the first ion conducting material and the second ion conducting material have different molar ratios of the hydrophilic repeating units and the hydrophobic repeating units.According to the ion exchanging membrane, it is possible to improve overall efficiency of the energy storage system by improving both performance efficiency and voltage efficiency of the energy storage system due to excellent ion-conductivity performance and reduced membrane resistance and ensure durability of the energy storage system by having excellent morphological stability and reducing a crossover of vanadium ions.
