Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on a winding axis to define a core and an outer circumference. The first electrode includes a first active material portion coated with an active material layer and a first uncoated portion not coated with an active material layer along a winding direction. At least a part of the first uncoated portion is defined as an electrode tab by itself. The first uncoated portion includes a first portion adjacent to the core of the electrode assembly, a second portion adjacent to the outer circumference of the electrode assembly, and a third portion interposed between the first portion and the second portion. The first portion or the second portion has a smaller height than the third portion in the winding axis direction.

Abstract: A battery includes an electrode assembly including a first electrode, a second electrode and a separator between the first electrode and the second electrode, the first electrode, the second electrode and the separator being wound around a winding axis to define a core and an outer peripheral surface. The first electrode and the second electrode include a first uncoated region and a second uncoated region along a winding direction, respectively, and an active material layer coating is absent in the first uncoated region and the second uncoated region. The battery further includes a housing receiving the electrode assembly through an opening formed at a bottom, a first current collector coupled to the first uncoated region and disposed within the housing, a cap covering the opening, a spacer interposed between the cap and the electrode assembly to fix the electrode assembly and seal the housing, and a terminal electrically connected to the second uncoated region.

Abstract: Provided are an electrode assembly, a battery, and a battery pack and vehicle including the same. An electrode assembly, in which a first electrode, a second electrode, and a separator interposed therebetween are wound about an axis to define a core and an outer circumferential surface. At least one of the first electrode and the second electrode includes, at a long side end portion, an uncoated portion exposed beyond the separator in a direction of the axis. At least a part of the uncoated portion is bent in a radial direction of the electrode assembly to define a bent surface region having overlapping layers of the uncoated portion. The bent surface region includes a welding target region having a number of the overlapping layers of the uncoated portion, and the welding target region extends along a radial direction of the electrode assembly.

Abstract: A battery includes an electrode assembly including a first uncoated region and a second uncoated region; a battery housing accommodating the electrode assembly and electrically connected to the second uncoated region; a cap to cover an open portion on bottom of the battery housing; a first electrode terminal passing through a partially closed portion of the battery housing and being electrically isolated from the battery housing; and a first current collector coupled to the first uncoated region and connected to the first electrode terminal.

Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is 10 or more in the winding axis direction of the electrode assembly.

Abstract: An exemplary embodiment provides an intruder detection method capable of accurately detecting an intruder and estimating an abnormal behavior of the intruder even when viewpoints of acquired images are different from each other. An intruder detection method is suitable for being performed by an intruder detection device for detecting an intruder based on images and includes: receiving input images acquired by multiple cameras; extracting feature maps associated with a plurality of viewpoints by applying the input images to a plurality of convolutional neural networks provided separately for the plurality of viewpoints of the images; and detecting the intruder based on the feature maps associated with the plurality of viewpoints.

Abstract: Provided is a cell frame structure comprising: a rectangular panel-shaped outer frame having a rectangular opening in the center; and a rectangular inner frame, the inner frame interlocking onto the rear surface of the outer frame around the opening thereof to form a flow cell. The flow cell is preferably assembled into a cell frame by the inner frame interlocking onto the rear surface of the outer frame while covering the rim of a bipolar plate, the front-side rim of which is seated around the rear surface opening of the outer frame.

Abstract: A work suit having a lifesaving function is provided where the work suit is made of two or more sheets of fabric, at least one variable contact tube keeping air in an amount smaller than a maximum capacity is formed in the uppermost part of a side of the work suit that corresponds to the girth of the body of a wearer, and when the variable contact tube gets into water, air in a lower portion is moved up by water pressure such that the thickness of an upper portion changes to the thickness when the variable contact tube is fully filled with air, so the variable contact tube come is in close contact with the body of the wearer.

Abstract: A belt clip assembly for use with a belt comprises a clip having first and second members defining a gap for slidably engaging the belt, a latch pivotally connected to a receptacle of the second member of the clip to pivot with respect to the second member. The latch has a flap member that has first and second flaps formed at a predetermined angle. The first flap extends toward the first member at an angle with respect to the second member to prevent the belt from disengaging from the clip. The belt clip assembly also has an actuating member extended through and slidably located in the second member of the clip. The actuating member has first and second ends, wherein the second end actuates the second flap when the first end is depressed. The latch has a pivot axle disposed at a joint formed by the first and second flaps and has a spring disposed in surrounding relation to the pivot axle to bias the latch in a closed position to prevent the belt from disengaging from the clip.
