An object of the present embodiment is to provide a high-performance secondary battery in which swelling is suppressed and the cycle characteristics are more excellent. The present embodiment is a secondary battery having an electrode element in which a positive electrode and a negative electrode are arranged to face each other, an electrolytic solution, and an outer package that contains the electrode element and the electrolytic solution, and the negative electrode includes lithium, An anode active material containing an alloyable metal (a), a metal oxide (b) capable of occluding and releasing lithium ions, and a carbon material (c) capable of occluding and releasing lithium ions is selected from polyimide and polyamideimide. The secondary battery is bound to a negative electrode current collector by at least one selected from the group consisting of a compound represented by any one of the predetermined formulas. |
