PROBLEM TO BE SOLVED: To provide a power storage device capable of suppressing reduction in charge/discharge efficiency.SOLUTION: In an organic electrolyte containing a fluorine compound, a positive electrode composed of a positive electrode current collector and a positive electrode active material, and a negative electrode composed of a negative electrode current collector and a negative electrode active material. A power storage device is characterized in that an electrodeposited aluminum foil whose surface (111) crystalline orientation is preferentially performed is used as the positive electrode current collector, and a potential applied to the positive electrode is 3.5 V (vs.Li/Li +) or more and 4.5 V(vs. Li/Li +) or less. |
