NONAQUEOUS LITHIUM STORAGE ELEMENT

A lithium storage element contains a positive electrode that contains a lithium compound other than an active material, a negative electrode, a separator, and a nonaqueous electrolytic solution containing lithium ions, for which an active material is applied on both surfaces of a nonporous positive...

Beschreibung
Zusammenfassung:	A lithium storage element contains a positive electrode that contains a lithium compound other than an active material, a negative electrode, a separator, and a nonaqueous electrolytic solution containing lithium ions, for which an active material is applied on both surfaces of a nonporous positive electrode power collector, and a negative electrode active material capable of storing and releasing lithium ions is applied on both surfaces of a nonporous negative electrode power collector. The relationships 0.85 ‰¤ C x1 /C y1 ‰¤ 1.15, 0.85 ‰¤ A x1 /A y1 ‰¤ 1.15, 0.80 ‰¤ (A x1 + C x1 )/(A y1 + C y1 ) ‰¤ 1.20, 0.1 ‰¤ C x2 (g/m 2 ) ‰¤ 18, 0.1 ‰¤ C y2 (g/m 2 ) ‰¤ 18, 0.60 ‰¤ C y2 /C x2 ‰¤ 1.70, and 0.60 ‰¤ C x2 /C y2 ‰¤ 1.70 are satisfied, where C x1 is the basis weight of the positive electrode active material layer C x surface, C y1 is the basis weight of the other positive electrode active material layer C y surface, A y1 is the basis weight of the negative electrode active material layer A y surface facing opposite the C y surface, A x1 is the basis weight of the other negative electrode active material layer A x surface, C x2 is the lithium compound amount per area of the C x surface, and C y2 is the lithium compound amount per area of the C y surface.
