摘要： The present disclosure provides a flow battery comprising a flexible lithium ion conductive film having durability against a highly reductive non-aqueous electrolyte liquid. The flow battery according to the present disclosure comprises a first non-aqueous electrolyte liquid, a first electrode, a second electrode, and a lithium ion conductive film. The first non-aqueous electrolyte liquid contains lithium ions and further biphenyl, phenanthrene, stilbene, triphenylene, anthracene, acenaphthene, acenaphthylene, fluorene, fluoranthene, o-terphenyl, m-terphenyl, or p-terphenyl. The lithium ion conductive film comprises a composite body. The composite body contains a lithium ion conductive polymer and polyvinylidene fluoride. The lithium ion conductive polymer includes an aromatic ring into which a lithium salt of an acidic group has been introduced. The lithium ion conductive polymer and the polyvinylidene fluoride have been mixed with each other homogeneously in the composite body.

摘要： A flow battery includes a first liquid containing a first nonaqueous solvent; a first electrode immersed in the first liquid; a second electrode which is a counter electrode to the first electrode; and a separator separating the first electrode from the second electrode. The separator includes a solid electrolyte containing: a metal compound and a nonionic polymer which includes a poly(alkylene oxide) and cross-linking points. At least one of alkylene oxide units forming the poly(alkylene oxide) is composed of a tetramethylene oxide unit.

摘要： The flow battery according to the present disclosure comprises a first non-aqueous liquid, a first electrode in contact with the first non-aqueous liquid, a second electrode which serves as a counter electrode of the first electrode, and a lithium ion conductive film which separates the first electrode and the second electrode from each other. The lithium ion conductive film is formed of a polymer base material containing an ionic polymer. The polymer base material has an interspace which communicates with an outside thereof. The polymer base material is formed of at least one kind of resin selected from the group consisting of a thermosetting resin and a thermoplastic resin which has a melting point of not less than 150 degrees Celsius. The ionic polymer is contained in an inside of the interspace of the polymer base material. The ionic polymer is represented by where n1 and n2 are, each independently, natural numbers of not less than 1, or where m1, m2, n1, and n2 are, each independently, natural numbers of not less than 1. The flexible lithium ion conductive film having a low swelling property when in contact with a non-aqueous liquid.
