To provide a flow battery capable of suppressing the crossover of redox species.SOLUTION: A flow battery 100 in an embodiment includes: the negative electrode 10; the positive electrode 20; a first fluid 12 in contact with the negative electrode 10; a second fluid 22 in contact with the positive electrode 20; and a lithium-ion conductive film 30 that is placed between the first fluid 12 and the second fluid 22. At least one of the first fluid 12 and the second fluid 22 contains redox species and lithium-ion. The lithium-ion conductive film 30 has an inorganic material containing zeolite.SELECTED DRAWING: Figure 1 【課題】酸化還元種のクロスオーバーが抑制されたフロー電池を提供する。【解決手段】本開示の一態様におけるフロー電池１００は、負極１０と、正極２０と、負極１０に接している第１液体１２と、正極２０に接している第２液体２２と、第１液体１２と第２液体２２との間に配置されたリチウムイオン伝導膜３０とを備える。第１液体１２及び第２液体２２の少なくとも一方は、酸化還元種及びリチウムイオンを含む。リチウムイオン伝導膜３０は、ゼオライトを含む無機部材を有する。【選択図】図１
