Pouch Case and the Method of Manufacturing the Pouch Type Secondary Battery Including the Same
A method of manufacturing a pouch type secondary battery according to an exemplary embodiment of the present disclosure includes the steps of: accommodating an electrode assembly in a space between an upper case and a lower case; and thermally fusing edge parts of the upper case and the lower case to each other, wherein edge parts of the upper case and the lower case each include a substrate layer, a metal layer and a sealing layer that are sequentially stacked, and wherein before the step of thermally fusing, the method further includes forming a plurality of grooves on one surface of at least one sealing layer of each of the upper case and the lower case.
Pouch for secondary battery and die for forming the same
Provided are a pouch for a secondary battery, which is capable of minimizing a folded area of a bridge part of the pouch that is manufactured by folding two accommodation parts to overlap each other, and a die for forming the pouch for the secondary battery. The pouch for the secondary battery includes a lower accommodation part accommodating an electrode assembly therein, an upper accommodation part covering an opening of the lower accommodation part, and a bridge part connecting the lower accommodation part to the upper accommodation part. When the lower accommodation part and the upper accommodation part are unfolded, a height of the bridge part, which is measured from a bottom surface of the lower accommodation part, is lower than that of the lower accommodation part, which is measured from the bottom surface of the lower accommodation part.
Deep pouch cell and method of manufacturing same
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.
COMPOSITE COVER MADE OF HYBRID FIBER REINFORCEMENTS
A composite component includes a substrate including a first region and a second region. A plurality of first fiber tows is arranged in the first region and including non-conductive filaments. First stitches attach the plurality of first fiber tows to a first surface of the substrate. A plurality of second fiber tows are arranged in the second region and including conductive filaments. Second stitches attach the plurality of second fiber tows to the first surface of the substrate.
INSTALLATION FOR PRODUCING A POLYMER MELT AND USE OF SUCH AN INSTALLATION FOR PRODUCING A POLYMER MELT FOR A POROUS FILM
An installation for producing a polymer melt for a porous film, in particular for a membrane film, comprises a planetary roller extruder. Said extruder is used to produce a flowable polymer melt from thermoplastics. The planetary roller extruder has a filling opening and a discharge side for delivering the polymer melt. A melt pump is further provided. The discharge side of the planetary roller extruder is connected to a downstream inlet side of the melt pump for further conveying the polymer melt. The connection is in the form of a pressure channel shielded from the ambient atmosphere or a pressure line shielded from the ambient atmosphere. The planetary roller extruder and the melt pump are designed and/or can be driven in such a manner that the polymer melt is applied or can be transferred under pressure at the melt pump on the inlet side.
Molded article and manufacturing method thereof
A molded article may include a composite wall portion that is composed of a resin substrate and a wood insert embedded in the resin substrate. The wood insert is integrated with the resin substrate in a boundary portion defined as a joining portion of an end surface of the wood insert and an end surface of the resin substrate with its inner and outer surfaces substantially exposed on inner and outer surfaces of the composite wall portion.
Heat exchanger plate assembles for electrified vehicle battery packs
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.
POUCH-TYPE SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME
A pouch-type secondary battery and a method of manufacturing same are capable of completely protecting a metal layer from moisture or air by forming an insulating coating layer including a conformal coating layer on the metal layer exposed at a cut surface of a battery case. The method includes a first step of preparing a battery case including an upper case and a lower case by cutting a laminate sheet including an outer coating layer, a metal layer, and an inner coating layer; a second step of receiving an electrode assembly between the upper case and the lower case; a third step of forming a sealing portion by contacting outer peripheries of the upper case and the lower case; and a fourth step of forming a conformal coating layer on a side surface of the sealing portion so as to prevent exposure of the metal layer.
