Document Type and Number:
Japanese Patent JP6922355
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a novel electrolyte solution for an aqueous solution based lithium secondary battery, which enables the expansion of a potential window.SOLUTION: An aqueous solution based lithium secondary battery 20 comprises: a positive electrode 22; a negative electrode 23; and an aqueous solution-based electrolyte solution 27. The aqueous solution-based electrolyte solution 27 contains, as an electrolyte, a water-soluble 2 lithium salt having a divalent organic acid structure, which is an aqueous solution prepared by dissolving the electrolyte at a concentration of 0.5 mol/L or more.SELECTED DRAWING: Figure 1
