Abstract: A battery pack includes a plurality of cell units each including at least one battery cell and a cell cover surrounding and supporting the at least one battery cell, and a pack case accommodating and supporting the plurality of cell units in an internal space, wherein the cell cover includes: a pair of side cover portions covering one surface and the other surface of the at least one battery cell, and a cap portion connecting the pair of side cover portions and covering an upper portion of the at least one battery cell, and further includes a gas cutoff portion disposed to be adjacent to the cap portion at an end of the cell cover in a longitudinal direction.

Abstract: A battery pack according to an embodiment of the present disclosure can include at least one battery module with a plurality of battery cell stacks. The battery pack can include a pack frame that houses the battery module and a vent flow path through which gas containing dust generated from the battery module moves. A final filter of the battery pack can filter the dust before the gas containing the dust is discharged to the outside of the battery pack. The battery pack can include a primary filter that is provided at a point where the direction of the vent flow path changes, and primarily filters the dust before the final filter.

Abstract: A battery pack includes a battery cell stack, a frame, a cooling part, an elastic member, and a sealing member. The frame houses the battery cell stack. The cooling part is disposed on the battery cell stack, and includes a coolant housing member having an upper plate and a lower plate. The elastic member is disposed in the inner space of the coolant housing member, and the sealing member that at least one through hole formed in the lower plate of the coolant housing member and is meltable by an increase in the temperature of the battery cell. A coolant is housed in a space between the elastic member and the lower plate of the coolant housing member, and the elastic member expands as the coolant is housed.

Abstract: A battery module according to one embodiment of the present disclosure includes a battery cell stack including a plurality of stacked battery cells; and at least one cooling member arranged on at least one of both side surfaces of the battery cell stack or between the plurality of battery cells. The cooling member includes a cooling channel that is a space inside the cooling member where a coolant flows, and an air gap that is an empty space separated from the cooling channel.

Abstract: A battery assembly includes multiple battery cells, and a cooling member interposed between the multiple battery cells. The cooling member includes a main body including a coolant flow path that allows coolant to flow therein, an inlet that communicates with the coolant flow path and allows the coolant to flow in, and an outlet that communicates with the coolant flow path and allows the coolant to flow out. The inlet and the outlet extend from one surface of the main body corresponding to a venting direction of the multiple battery cells.

Abstract: A battery pack includes at least one battery module; a pack frame accommodating the battery module; a venting hole formed in the pack frame; and a mesh structure covering the venting hole, wherein a duct member is formed between the mesh structure and the pack frame, and an adsorption member is formed on the duct member.

Abstract: A battery pack includes a plurality of battery modules; a pack frame that houses the plurality of battery modules; end plates that cover the open front and rear surfaces of a battery cell stack; and a blocking member located between the pack frame and the end plate, wherein the blocking member comprises a frame member; an opening formed in the frame member; and a blocking plate that covers the opening. The blocking plate moves in a specific direction to open and close the opening.

Abstract: Disclosed is a mobile terminal, by which extensibility of an antenna pattern and radiation efficiency of an antenna can be increased. The present invention includes a display, a frame configured to support a back of the display, a first antenna to be provided to at least one side of a top portion and a bottom portion of the frame, a rear case to attach to a back of the frame, a second antenna provided to at least one of an inner side and an outer side of the rear case, and a third antenna configured in a beam shape to be attached to at least one of a right lateral side and a left lateral side of the frame, the third antenna configured to be electrically connected to either the first antenna or the second antenna.

Abstract: A mobile terminal includes: a main body with a top surface, a bottom surface, and a back surface; and a case surrounding the main body, the case including: a top side portion covering the top surface of the main body; a backside portion including a first backside portion positioned in the upper part and covering the back of the main body and a second backside portion positioned below the first backside portion and covering the back of the main body; and a bottom side portion covering the bottom surface of the main body, wherein the top side portion, first backside portion, second backside portion, and bottom side portion may be made of a metal material, and separated from one another by a non-metal member, and the non-metal member may have a light-emitting portion that gives off light.
