Abstract
There is provided a cap assembly for a rectangular battery comprising a cap cover in which a vent hole is formed, a positive electrode terminal which has a through hole leading to the discharge hole and combines with the upper portion of the cap cover having an insulating plate interposed therebetween, a positive electrode tab connected to a positive electrode of an electrode assembly, a conductive safety vent support having a hollow rivet protrusion passing through the vent hole of the cap cover and the through hole of the positive electrode terminal to be coupled to the positive electrode terminal, and a conical conductive safety vent whose upper circumferential portion combines with the bottom surface of the safety vent support to seal the hollow of the rivet protrusion, and whose vertex contacts the upper surface of the positive electrode tab, wherein the vertex of the safety vent separates from the positive electrode tab when the internal pressure of the battery increases to a predetermined level.
