The cap assembly is coupled to an open end of a battery can, and includes a top cap disposed on an uppermost portion of the cap assembly in a protrusive form to form a positive electrode terminal; a safety vent disposed below the top cap to deform a shape when an internal pressure of the battery can increases; a gasket configured to surround edges of the top cap and the safety vent; and a screen member interposed between the top cap and the safety vent and having an edge surrounded by the gasket, the screen member being at least partially configured in a mesh form.",
