Abstract
A cylindrical secondary battery includes a first gasket and a second gasket having a modified shape to secure hermetic sealability and insulation. The battery includes a cylindrical can for receiving an electrode assembly, a cap assembly located at the upper part of the cylindrical can, a first gasket for covering outer circumferential edges of a top cap and a venting member of the cap assembly, a current interrupt device (CID) located at the lower part of the cap assembly, and a second gasket along the outer circumferential edge of the current interrupt device. An upper end portion of the first gasket covers the upper surface of the outer circumferential edge of the top cap, and includes a recessed portion in its inner surface configured to prevent the first gasket from being brought into tight contact with the upper surface of the outer circumferential edge of the top cap.
