Abstract
A secondary battery includes a partition, a negative electrode, a positive electrode, a first aqueous electrolytic solution, and a second aqueous electrolytic solution. The partition separates a first space and a second space from each other and allows a metal ion to pass therethrough between the first space and the second space. The negative electrode is disposed in the first space. The positive electrode is disposed in the second space. The first aqueous electrolytic solution is contained in the first space. The second aqueous electrolytic solution is contained in the second space. The second aqueous electrolytic solution has a pH lower than the first aqueous electrolytic solution.
