Title:
ELECTROCHEMICAL DEVICE INCLUDING THREE-LAYER SYSTEM ELECTROLYTIC SOLUTION
Document Type and Number:
WIPO Patent Application WO/2020/241686
Kind Code:
A1
Abstract:
[Problem] To provide an electrochemical device that can be used for both water-soluble and water-insoluble active materials, and that enables ion transport effectively even without using a solid electrolyte membrane. [Solution] This electrochemical device includes: (a) at least one pair of a positive electrode and a negative electrode; (b) an aqueous layer including one of a positive electrode electrolytic solution and a negative electrode electrolytic solution; (c) a non-aqueous layer including the other of the positive electrode electrolytic solution and the negative electrode electrolytic solution; and (d) an emulsion layer including both the positive electrode electrolytic solution and the negative electrode electrolytic solution, and being interposed between the aqueous layer and the non-aqueous layer without any intermixing therewith.
