Original Abstract Submitted
A cylindrical secondary battery includes: an electrode assembly including a first electrode plate, a separator, and a second electrode plate; a case accommodating the electrode assembly and electrically connected to the second electrode plate; a terminal passing through a lower surface of the case and electrically connected to the first electrode plate; and a cap plate sealing an upper end portion of the case and having a vent. The vent is a thinner portion of the cap plate than other regions thereof and has a central notch having a ring shape and being at a central portion of the cap plate and an inner peripheral notch having a line shape extending from the central notch toward an edge of the cap plate.
