Title:
二次電池
Document Type and Number:
Japanese Patent JP7420271
Kind Code:
B2
Abstract:
A secondary battery includes a partition, a positive electrode, a negative electrode, a positive electrode electrolytic solution, and a negative electrode electrolytic solution. The partition is disposed between a positive electrode space and a negative electrode space, and allows a metal ion to pass therethrough. The positive electrode is disposed in the positive electrode space and is an electrode which the metal ion is to be inserted into and extracted from. The negative electrode is disposed in the negative electrode space and is an electrode which the metal ion is to be inserted into and extracted from. The positive electrode electrolytic solution is contained in the positive electrode space and includes an aqueous solvent. The negative electrode electrolytic solution is contained in the negative electrode space and includes an aqueous solvent. The negative electrode electrolytic solution has a pH that is higher than a pH of the positive electrode electrolytic solution. The partition includes a cation exchange membrane that is ion exchanged with the metal ion.
