Abstract
A button-type secondary battery includes an electrode assembly; a lower can in which the electrode assembly is disposed and on which a first screw thread is defined on an outer circumferential surface thereof; an upper can which is configured to cover an opening of an upper end of the lower can and on which a second screw thread corresponding to the first screw thread is defined on an inner circumferential surface thereof; and an insulator interposed between the upper can and the lower can to prevent the upper can and the lower can from being electrically short-circuited with each other, wherein an electrode tab extending from an electrode of the electrode assembly is in contact with the upper can.
