Abstract: The object of the present invention is to provide an electric power storage device using an aqueous electrolytic solution that is safe even if the device is damaged while being used and the electrolytic solution leaks out from the battery housing. Specifically, the object of the present invention is to provide a secondary battery having both excellent safety and excellent cycle characteristics. The present invention is an aqueous secondary battery, wherein at least either of the positive electrode or the negative electrode comprises a compound (I) having a naphthalenediimide structure or a perylenediimide structure as an active material.
