え、電池の劣化を進めてしまう問題点を有していた。A battery using an organic electrolytic solution is affected by discharge characteristics, storage characteristics, and the like, due to moisture present inside the battery, particularly, moisture contained in the electrolytic solution. Moisture is contained as an impurity in the organic electrolytic solution, and this causes a chemical reaction with a solute constituting the organic electrolytic solution to generate an acid. This acid causes elution of the positive electrode, which causes a problem that the discharge capacity is reduced during storage and use for a long period of time, particularly during storage in a high-temperature environment. Further, the acid has a problem that it also affects battery constituent members such as a separator and a gasket which do not contribute to the electromotive reaction, and promotes deterioration of the battery.
