Abstract
A nonaqueous lithium-type power storage element comprising a positive electrode, a negative electrode, a separator, and a nonaqueous electrolytic solution containing lithium ions. The negative electrode has: a negative electrode collector; and a negative electrode active material layer containing a negative electrode active material, said negative electrode active material layer being provided on one surface or both surfaces of the negative electrode collector. The negative electrode active material contains a carbonaceous material capable of storing or releasing lithium ions. Furthermore, the positive electrode has: a positive electrode collector; and a positive electrode active material layer containing a cathode active material, said positive electrode active material layer being provided on one surface or both surfaces of the positive electrode collector. The positive electrode active material contains activated carbon. Also, the positive electrode active material layer contains one or more compounds selected from formulas (1) to (3) in an amount of 1.60×10to 300×10mol/g per unit mass of the positive electrode active material layer. LiX—ORO—XLi (1) LiX—ORO—XR(2) RX—ORO—XR(3) (In the formulas, RR, RX, and Xrepresent groups defined in the specification of the application.)
