    Abstract: PROBLEM TO BE SOLVED: To prevent degradation of battery capacity. SOLUTION: A positive electrode 2 and a negative electrode 4, a nonaqueous electrolyte solution interposed between the positive electrode and the negative electrode, a collector 7 out of contact with the positive electrode and the negative electrode and capable of doping/dedoping lithium ion, and a positive electrode can 3 and a negative electrode can 5 sealing the positive electrode 2, the negative electrode 4, the nonaqueous electrolyte solution and the collector 7 are provided. As the collector 7 has a potential inferior to the oxidation- reduction potential of metal ion contained in an active material of the positive electrode, the metal ion eluted from the positive electrode 2 on the surface of the negative electrode 4 charged/discharged is prevented from precipitating and forming a coating to avoid degradation of battery capacity.
