Abstract: An electrode active material for non-aqueous secondary batteries containing a compound represented by formula (1) is a material that is less likely to dissolve in an electrolyte during charge and discharge, and that exhibits an excellent discharge capacity and excellent charge-and-discharge cycle characteristics: the compound represented by formula (1) wherein Y1 and Y2 are identical or different and represent an oxygen atom, a sulfur atom, or a selenium atom, R1 to R8 are identical or different and represent an oxygen atom or a group represented by —OLi, R9 to R12 are identical or different and represent a hydrogen atom or an organic group, and bonds that are each represented by a solid line and a dashed line indicate a single bond or a double bond.

Abstract: A rocking-chair nonaqueous secondary battery, which uses an ion other than monatomic ions as a charge carrier, and in which the ion moves in and out of both the positive electrode and the negative electrode, can be provided by using a nonaqueous secondary battery electrolyte comprising a salt containing a charge carrier comprising a molecular ion. The nonaqueous secondary battery further comprises a positive electrode containing a positive electrode active material, and a negative electrode containing a negative electrode active material, wherein the positive electrode active material and the negative electrode active material are both materials that allow doping and dedoping of molecular anions (e.g., conductive polymers, organic radical polymers, polymers having a ferrocene skeleton, conductive carbon materials, or organic sulfur compounds), or the positive electrode active material and the negative electrode active material are both materials that allow doping and dedoping of molecular cations (e.g., inorganic active materials, redox active molecules having a carbonyl group, redox active molecules having an imine skeleton, or redox active molecules containing a sulfur atom).
