摘要：
A secondary battery capable of suppressing resistance rise even after repeated charge and discharge is provided. The secondary battery includes a cathode, an anode, and an electrolytic solution. The anode contains titanium-containing lithium composite as an anode active material, and the electrolytic solution contains cyclic disulfonic acid anhydride.
