Abstract
The present disclosure relates to a cylindrical secondary battery, and more specifically, to a cylindrical secondary battery capable of suppressing the upward movement of an electrode assembly inside a battery can even when the battery can is heated. A cylindrical secondary battery according to the present disclosure includes a battery can having an open top end portion, an electrode assembly accommodated in the battery can, a top cap assembly coupled to the top end portion of the battery can and formed with a gas outlet for discharging gases generated inside the battery can, and a thermal expansion tape attached to an upper region of the inner wall of the battery can and expanding when the battery can is heated, thereby suppressing the upward movement of an electrode assembly accommodated in the battery can even when heat is applied to the battery can, which may prevent a gas outlet formed at the top of the battery can from being blocked.
