Abstract

The invention relates to the technical field of rupture disks, and discloses a double-open-type rupture disk which is arranged in a top cover plate of a lithium battery and comprises a disk body, the disk body comprises a continuous-sheet-shaped rupture area and a connecting ring which is in butt joint with the periphery of the rupture area in a surrounding mode and welded to the top cover plate, wherein the connecting ring seals the periphery of the rupture area, and the thickness of the rupture area is smaller than that of the connecting ring; a notch groove is formed in the rupture area and divides the rupture area into two or more than two independently-isolated rupture subareas, and the two ends of the notch groove extend and penetrate to the periphery of the rupture area; the thickness of the rupture area is smaller than that of the connecting ring; when the rupture disk is blasted, blasting can be conducted in the rupture area; the rupturearea is provided with the notch groove, and the notch groove deviates from the welding position, so that the phenomenon that the rupture disk is blasted in the welding process is avoided; and the rupturearea is divided into two or more than two independently-isolated rupture subareas through the notch groove, so that double-open type precise blasting is achieved.

Description

technical field [0001] The patent of the present invention relates to the technical field of lithium batteries, in particular, to a bursting disc for double-opening bursting. Background technique [0002] At present, with the continuous development of power batteries and energy storage technologies, lithium batteries have been widely used due to their excellent characteristics such as high capacity. [0003] The lithium battery includes a casing, a top cover sheet, and a battery cell, etc., wherein the battery cell is placed inside the casing, the upper end of the casing has an upper end opening, and the top cover sheet closes the opening at the upper end of the casing, and the top cover sheet is provided with a Port, the lithium battery realizes the power supply to the outside through the port. [0004] The battery cell is used as the power storage element of the lithium battery. When the lithium battery is in use, due to factors such as the charger and the internal chemic...
