This electricity-storage battery is provided with a positive-electrode electrolyte solution (22) containing the following: a manganese redox material and an amine that can be represented by general formula (1). In general formula (1), n represents an integer from 0 to 4; R 1 , R 2 , R 3 , and R 4 each independently represent either a hydrogen atom, a methyl group, or an ethyl group; and if n is 0, at least one of R 1 , R 2 , R 3 , and R 4 represents a methyl group or an ethyl group. |
