Beschreibung
Zusammenfassung:	A cylindrical battery includes a housing having an accommodating space; and a negative electrode sheet, a first separator, a positive electrode sheet, and a second separator that are wound multiple turns forming an electrode core. The housing is co-axial with the electrode core that is disposed in the accommodating space. The positive electrode sheet includes a positive electrode material layer and a positive electrode foil layer. The negative electrode sheet includes a negative electrode material layer and a negative electrode foil layer. Some of the wound turns of the positive electrode foil layer extends toward an end of the housing to form a positive electrode tab. Some of the wound turns of the negative electrode foil layer extends toward another end of the housing to form the negative electrode tab.
