Abstract: A battery includes an electrode assembly defining a core and an outer circumference by winding a first electrode, a second electrode, and a separator interposed therebetween around a winding center, each of the first electrode and the second electrode includes a first uncoated portion and a second uncoated portion on which an active material layer is not coated along the winding direction; a battery housing accommodating the electrode assembly through an opening formed on one side thereof; a cap including a venting portion, covering the opening, and electrically connected to the battery housing and the first uncoated portion; and a battery terminal penetrating one surface of the battery housing and electrically connected to the second uncoated portion.

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: 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: A battery includes an electrode assembly including a first electrode, a second electrode and a separator between the first electrode and the second electrode wound around a winding axis to define a core and an outer circumferential surface, the first electrode including a first uncoated region in which an active material layer is not coated along a winding direction; a housing accommodating the electrode assembly through an open portion at a lower end thereof; a first current collector coupled to the first uncoated region and disposed in the housing; a cap to cover the open portion; and a spacer between the first current collector and the cap and having a height corresponding to a distance between the first current collector and the cap.

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: A cylindrical battery cell includes a jelly-roll having a first electrode tab protruding upward and a second electrode tab protruding downward, a battery can configured to accommodate the jelly-roll through a top opening and electrically connected to the second electrode tab, a first current collecting plate coupled to the first electrode tab at an upper portion of the jelly-roll, an insulating shrink tube having a first cover portion for covering at least a part of the first current collecting plate and a second cover portion for covering a top end of an outer circumference of the jelly-roll, and a top cap electrically connected to the first current collecting plate and configured to cover the opening.

Abstract: Disclosed herein is an information notification device for a vehicle. The information notification device for a vehicle is a vehicle-mounted safety product, and enables shapes and characters or the like, adapted to indicate a direction, to be displayed in various manners by opening the trunk of a vehicle when a breakdown or accident of the vehicle has occurred, and thus the driver of the following vehicle can be rapidly and accurately notified of the emergency situation and a traffic lane to and along which the following vehicle needs to switch its lane and to travel can be indicated by a directional sign, thereby enabling the driver of the following vehicle to more safely and rapidly deal with the emergency situation.

Abstract: A memory cell array with an active region which has first portions and fifth portions which are at both ends thereof and a third portion which is the middle portion thereof. The first, third and fifth portions are parallel to each other with a certain spacing. The first and third portions are interconnected by a second portion sloped toward a side of the third portion. The third portion and fifth portions are interconnected by a fourth portion sloped upward from the other side of the third portion. Source regions are formed in the first and fifth portions and fifth portion of the active region. A drain region is formed in the third portion of the active region. Channel regions are formed in the second portion and fourth portion of the active region. Floating gates are disposed over each of the channel regions. A pair of control gates is disposed over the floating gates.

Abstract: Disclosed is a fuel injection system with a variable injection position, including an accelerating pedal, a throttle valve for regulating the amount of intake air in response to vehicle speed, a fuel distribution pipe, an injector fixed to the fuel distribution pipe, an accelerating lever which rotates in response to pedal effort of the accelerating pedal, a pinion which rotates in accordance with the rotation of the accelerating lever, and a rack which slides horizontally in response to the rotation of the pinion to vary the position of the injector that is fixed on the fuel distribution pipe.
