Abstract: A pouch-type battery case includes a cup portion, which accommodates therein an electrode assembly formed by stacking an electrode and a separator, and a plurality of die edges connecting an outer wall of the cup portion to a side extending from the outer wall. The die edges include a first region, which is rounded at a first radius (r1) of curvature and at which an electrode tab extending from the electrode is positioned, and a second region which is other than the first region and rounded at one or more second radii (r2, r3, r4) of curvature less than or equal to the first radius (r1) of curvature. The second region is divided into an inner region and an outer region with respect to the first region, and the radius (r2) of curvature in the inner region differs from the radii (r3, r4) of curvature in the outer region.

Abstract: A secondary battery case accommodates an electrode assembly having a structure in which electrodes and separators are alternately arranged, and includes a first cup having a recessed shape, a second cup having a recessed shape and provided on one side of the first cup, a first peripheral portion surrounding a perimeter of the first cup when the secondary battery case is unfolded, and a second peripheral portion surrounding a perimeter of the second cup when the secondary battery case is unfolded. The first peripheral portion includes a first cup-corresponding peripheral portion that corresponds to a width of the first cup, and the second peripheral portion includes a second cup-corresponding peripheral portion that corresponds to the second cup. The width of the first cup is greater than a length of the first cup-corresponding peripheral portion thereby reducing if not eliminated a bat-ear otherwise formed during manufacture.

Abstract: Disclosed are an exterior for a secondary battery and an apparatus and method for manufacturing the exterior for the secondary battery. According to one aspect of the present invention, a method for manufacturing an exterior for a secondary battery comprises: a first step of preparing a sheet and a mold in which a recess part (I) is formed; a second step of locating the sheet so that a portion of the sheet faces the recess part (I); and a third step of supplying a fluid from the side of the mold toward the recess part (I) to form a forming part having a shape corresponding to that of the recess part (I) in an area of the sheet, which is provided on the recess part (I).

Abstract: Provided is a pouch type battery case. The pouch type battery case include a cup part configured to accommodate an electrode assembly, which is formed by stacking electrodes and separators, therein and a plurality of die edges configured to connect an outer wall of the cup part to a side extending from the outer wall. At least one die edge includes a first area formed to be rounded with a first curvature radius and a second area formed to be rounded with a second curvature radius less than the first curvature radius.

Abstract: A case for a secondary battery, in which an electrode assembly having a structure, in which electrodes and separators are alternately disposed, is accommodated, includes: a first recess part and a second recess part, each of which has a recessed shape; a circumferential part configured to surround a circumference of each of the first recess part and the second recess part when the case is unfolded; and a connection part provided between the first recess part and the second recess part to connect the first recess part to the second recess part, wherein, when the case is unfolded, the connection part has a shape that is recessed from each of the first recess part and the second recess part in one direction.

Abstract: A secondary battery case includes a, recess part recessed downward and a sealing part provided around the recess part when the secondary battery case is unfolded. At least portions of the sealing part are attached to each other to seal inner surfaces of the recess part from an outside. A secondary battery includes an electrode assembly and the secondary battery case. The recess part of the secondary battery case has a width that corresponds to a thickness of the electrode assembly.

Abstract: A driver assistance system and method are disclosed.

Abstract: A driver assistance system (DAS) includes a camera configured to be installed on the vehicle to have a field of view and obtain image data, a radar configured to be installed on the vehicle to have a field of view outside and obtain radar data and a controller configured to include a processor to process the image data obtained by the camera and the radar data obtained by the radar data, and the controller identifies an object based on at least one of the image data and the radar data, determines a risk for the object by determining collision possibility with the identified object, and determines driving position of the vehicle within a driving lane based on the risk for the object.

Abstract: A cathode active material for a lithium secondary battery includes lithium transition metal oxide particles, wherein the lithium transition metal oxide particles may include first lithium transition metal oxide particles (first particles) including an interparticular pore and second lithium transition metal oxide particles (second particles) having an average particle diameter within a range of a diameter of the interparticular pore, measured by mercury intrusion porosimetry. By including first particles including an interparticular pore and second particles having an average particle diameter within a range of a diameter of the interparticular pore measured by mercury intrusion porosimetry, the cathode active material may have a reduced interparticular pore present therein. Accordingly, the cathode active material may have an improved pellet density. Consequently, when a lithium secondary battery is manufactured using the cathode active material, the energy density thereof may improve.
