Abstract: Discussed is a battery that may include at least one battery module including at least one battery cell, a case tray configured to support the at least one battery module, a case cover coupled with the case tray to cover the at least one battery module, a sealing gasket disposed between the case tray and the case cover to prevent penetration of moisture or foreign substance into the at least one battery module, and a reinforcing unit provided to the case cover to be disposed adjacent to the sealing gasket and configured to prevent twisting of the case cover when the case tray and the case cover are coupled.

Abstract: The present invention relates to a method for preparing an inorganic compound using desulfurization gypsum for reducing greenhouse gas emissions, and, more specifically, to a method for preparing an inorganic compound, in which calcium sulfate and calcium carbonate, which have various uses as construction materials and the like, can be prepared using, as raw material, desulfurization gypsum which, being a recycled resource, is industrial waste, and an extraction agent, and the extraction agent can be reused after separation, and thus, compared to existing processes, greenhouse gases and manufacturing costs can be remarkably reduced.

Abstract: Discussed is a battery pack that may include at least one battery module including at least one battery cell; a case tray configured to support the at least one battery module; a tray cover coupled to the case tray; and at least one bushing gasket configured to connect the case tray and the tray cover and to support the case tray on a plurality of points.

Abstract: A refrigerator includes a body having a storage space; a door coupled with the body and for opening/closing the storage space, and an ice particle maker equipped in the door, wherein the ice particle maker includes a water feed nozzle for injecting water supplied from a water supply source into an ice particle making area; a cold air flow path for supplying cold air to the ice particle making area; and a dispenser for discharging ice particles made from the ice particle maker.
