Abstract
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.
