Title:
FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/220683
Kind Code:
A1
Abstract:
A flow battery according to the present disclosure is provided with: a first nonaqueous liquid; a first electrode in contact with the first nonaqueous liquid; a second electrode functioning as a counter electrode of the first electrode; and a lithium ion conducting film for isolating the first electrode and the second electrode from each other. The lithium ion conducting film is formed of a polymeric base material containing ionic polymers. The polymeric base material has gaps that communicatively connect to the outside. The polymeric base material is formed of at least one type of resin selected from a group consisting of a thermosetting resin and a thermoplastic resin having a melting point of 150°C or more. The ionic polymers are contained in the interiors of the gaps of the polymeric base material. The ionic polymers are represented by formula (AA) (each of n1 and n2 is independently a natural number equal to or greater than 1) or formula (BB) (each of m1, m2, n1, and n2 is independently a natural number equal to or greater than 1). The lithium ion conducting film has flexibility and does not easily swell when coming into contact with a nonaqueous solution.
