Abstract: A battery pack includes a battery module having at least one battery cell, a pack case configured to accommodate the battery module, and a connection guide unit provided on at least one side of the pack case and configured to be accessible to electrical members of two or more connection types.

Abstract: Provided is a method of manufacturing a light-emitting element, the method including positioning a substrate, forming a first separation layer, which includes a first sacrificial layer, an etching control layer on the first sacrificial layer, and a second sacrificial layer on the etching control layer, on the substrate, forming at least one first light-emitting element on the first separation layer, and separating the first light-emitting element from the substrate.

Abstract: A refrigerator includes a cabinet, an evaporator, a shroud, a grille panel coupled to a front surface of the shroud, and a blower fan module disposed between the grille panel and the shroud and configured to blow the cool air from the evaporator toward a freezing compartment. The blower fan module includes an installation frame defining a first plane that faces a rear surface of the grille panel, and a second plane that faces the front surface of the shroud, a hub part that is rotatably coupled to the second plane of the installation frame and faces an inlet hole of the shroud, and a blower impeller disposed in the hub part.

Abstract: A device for exhausting carbon dioxide includes: at least one carbon dioxide adsorber which is configured to be able to be electrically heated; and a heat radiating part of a heating device for heating an interior space. A carbon dioxide exhausting process is repeatedly performed. The carbon dioxide exhausting process includes: a first process of urging interior air to pass through the carbon dioxide adsorber and then to be introduced into an interior space; a second process of urging interior air to pass sequentially through the carbon dioxide adsorber and the heat radiating part in a state that the carbon dioxide adsorber is electrically heated and to be exhausted to an exterior space; and a third process of urging exterior air to pass sequentially through the heat radiating part and the carbon dioxide adsorber and then to be introduced into an interior space after the second process.
