Beschreibung
Zusammenfassung:	A cylindrical secondary battery includes a jelly-roll type electrode assembly, a cylindrical case, and a positive electrode tab and a negative electrode tab coupled to the jelly-roll type electrode assembly. The cylindrical secondary battery includes a plurality of quadrants. The plurality of quadrants are defined by dividing a horizontal cross section perpendicular to a winding axis of the jelly-roll type electrode assembly into a plurality of sections. The positive electrode tab and the negative electrode tab are positioned in a first quadrant of the plurality of quadrants.
