A receiving element for mounting pouch cells, has a base body, wherein, with respect to an object of receiving pouch cells securely and cost-effectively in a frame or housing, the base body is formed as a profile having a contact surface for contact against a sealing seam of a pouch cell.

An electrochemical pouch cell includes a pouch cell housing and an electrode assembly disposed in the housing. The housing is formed of a single blank that is progressively drawn to form first and second recesses in the sheet, where the first recess coincides with a portion of the second recess. The blank is then folded so that the recesses are aligned and open facing each other. The electrode assembly is disposed in the space defined within and between the recesses, and flange portions of the material surrounding the recesses are sealed together to form a sealed electrochemical cell in which one side of the cell is free of the flange. The progressive drawing process along with the configuration of the recesses allows the cell housing to have an increased depth relative to some conventional pouch cell housings.

A battery module includes a cell assembly including at least one battery cell; a module casing configured to accommodate the cell assembly; and a busbar assembly integrated by forming, by insert-injection molding, a busbar electrically connected to an electrode lead of the cell assembly, and a busbar frame configured to cover the cell assembly at least at one side thereof.

Disclosed is a method for manufacturing a secondary battery.

According to the present invention, a problem of weakening durability of a pouch, which may occur in a process of forming cups having different depths in the pouch may be solved.

This disclosure details exemplary battery pack designs for use in electrified vehicles or other electrified components. An exemplary battery pack may include a heat exchanger plate assembly having a metallic plate and a polymeric plate that are joined together to establish a coolant circuit therebetween. The metallic plate or the polymeric plate may include a protrusion that extends through an opening of the other of the metallic plate or the polymeric plate. The protrusion may either be crimped or heat staked to a surface surrounding the opening in order to join together the metallic plate and the polymeric plate of the heat exchanger plate assembly.

The present disclosure relates to a battery module that includes a housing having a first absorptive material configured to absorb a laser emission, a cover having a second absorptive material configured to absorb the laser emission, and a collar configured coupled to the housing and coupled to the cover via a laser weld. The collar includes a transparent material configured to transmit the laser emission through the collar and toward the housing or the cover.

A disclosed sizing roller apparatus for a folding process of a battery cell includes: a table fixing and supporting a battery cell; a base plate disposed on a side of the table; a plurality of sizing rollers disposed on the base plate and each having a rotation axis, which is inclined inward toward a folding portion of the battery cell, to press the folding portion of the battery cell in contact with the folding portion; and a plurality of air spray nozzles disposed on the base plate and spraying air to the plurality of sizing rollers.

A pack case includes: a first wall pressing a battery stack toward a second side in a stacking direction; and a second wall pressing the battery stack toward a first side in the stacking direction. At least one of the first wall and the second wall is a panel structure wall including a first metal plate, a second metal plate located outward of the first metal plate in the stacking direction and faces the first metal plate, and an interposed member interposed between and fixed to the first metal plate and the second metal plate. The interposed member has a lower density than a metal forming the first metal plate and the second metal plate.

Disclosed herein is a battery cell configured to have a structure in which an electrode assembly is mounted in a battery case made of a laminate sheet including a resin layer and a metal layer, and the battery case is provided with a sealed portion (an outer edge sealed portion), which is formed at the outer edge of a receiving part, in which the electrode assembly is mounted, by thermal welding in order to seal the battery case, wherein electrode terminals are located at an upper sealed portion, a lower sealed portion, or the upper sealed portion and the lower sealed portion, two or more sealed lines are formed in at least one of side sealed portions, which are adjacent to the upper sealed portion or the lower sealed portion, such that the sealed lines are spaced apart from each other and parallel to each other, the sealed lines are continuously formed from the outer edge end of the upper sealed portion to the outer edge end of the lower sealed portion in the longitudinal direction of the battery case, and the outer edge sealed portion, in which the sealed lines are formed, is bent between the sealed lines at an angle of 30 to 180 degrees.

A fiber-reinforced resin molded article is molded into a three-dimensional shape on the basis of a sheet-shaped base material containing a fiber-reinforced resin. The fiber-reinforced resin molded article includes three-way directed corner portions constituted by plate sections joined in three mutually different directions. The fiber-reinforced resin molded article includes wrinkles that protrude from the differently directed corner portions by folding the sheet base material, and thick-walled sections which are laminated at sites where at least the wrinkles are formed.
