摘要：
A secondary battery includes: a cathode including a cathode current collector and a first cathode active material layer provided on the cathode current collector; an anode including an anode current collector and a first anode active material layer provided on the anode current collector to face the first cathode active material layer and including a titanium-containing compound; an intermediate electrode provided between the cathode and the anode and including an intermediate current collector, a second anode active material layer provided on the intermediate current collector to face the first cathode active material layer and including the titanium-containing compound, and a second cathode active material layer provided on the intermediate current collector to face the first anode active material layer; and an electrolytic solution including a solvent and an electrolyte salt and having number of molecules of the electrolyte salt equal to or larger than number of molecules of the solvent.
