Abstract: A battery pack includes a battery cell and a casing configured to receive the battery cell. The casing has a vent hole configured to allow gas generated in the battery cell to be discharged therethrough, and a sound generator installed in the vent hole so as to block the vent hole. The sound generator is configured to allow the gas to pass therethrough, and generate a sound by the flow of the gas when the gas is discharged from the casing through the vent hole.

Abstract: The present disclosure relates to a can for a secondary battery and a secondary battery. The can for the secondary battery can include a can body, in which an electrode assembly accommodation part accommodating an electrode assembly are formed. The can body can be opened to one side. The secondary battery can include a cover to cover one end of the can body to seal an opening and in which a through-hole through which an electrode lead of the electrode assembly passes. The can body can include a body heat pipe that transfers heat so that the heat is dissipated through the can body when the heat generated in the electrode lead is transferred from the cover to the can body.

Abstract: The battery pack according to the present disclosure includes a cell module assembly, a pack case including a case body to receive the cell module assembly and a case cover coupled with the case body to package the cell module assembly, and a horizontal protruding rib protruding toward the cell module assembly in a direction parallel to a stack direction of cells in the cell module assembly at an inner lower end of the case body, wherein the horizontal protruding rib is a double rib structure including a first rib which is compressed by the cell module assembly to absorb a thickness tolerance of the cell module assembly, and an uncompressible second rib which is provided on an outer side of the first rib and disposed at a more rear position than the first rib to reinforce the first rib.

Abstract: A cell cartridge having a first pouch cell having a first fixing portion extending from a sealing portion thereof, a second pouch cell having a second fixing portion extending from a sealing portion thereof, and a cartridge configured to accommodate a cell stack formed by stacking the first pouch cell and the second pouch cell is provided. The first fixing portion is bent toward the second pouch cell to restrict movement of the second pouch cell. The second fixing portion is bent toward the first pouch cell to restrict movement of the first pouch cell.

Abstract: Disclosed is a battery pack, which includes: a battery module having at least one battery cell; a pack case having a case body for accommodating the battery module and a case cover configured to be welded to the case body to package the battery module; and at least one weld quality indicator provided on the case body of the pack case to inspect accuracy of welding.
