Title:
イオン交換膜、レドックスフロー電池
Document Type and Number:
Japanese Patent JP7393601
Kind Code:
B2
Abstract:
To provide an ion-exchange membrane that, when being used in a redox flow battery, provides excellent current efficiency and can suppress reduction in voltage efficiency. The ion-exchange membrane contains a fluorinated polymer having sulfonic acid-type functional groups and is characterized in that the difference (D - Dc) between the distance D between ion clusters measured by the small angle X-ray scattering method, and the diameter Dc of an ion cluster is larger than 0 and at most 0.50 nm.
