An apparatus for manufacturing a battery cell for processing a sealing part of a battery cell, the sealing part being formed on one side of a body part in which an electrode assembly is accommodated, includes: a support unit including a first support portion and a second support portion supporting the battery cell in different directions; and a pressing unit moving toward the support unit to bend the sealing part, wherein the first support portion reciprocates in a first direction, the second support portion reciprocates in a second direction, and the second direction is inclined with respect to the first direction.

Apparatus for manufacturing battery cell

A taping apparatus for a secondary battery, configured to adhere an adhesive member cut and provided as a single sheet to a secondary battery cell including an accommodating portion in which an electrode assembly is accommodated and a sealing portion folded in a direction of the accommodating portion and sealing an edge of the accommodating portion, includes a support unit supporting a portion of the adhesive member; and a roller unit continuously moving in at least one direction of the accommodating portion and the sealing portion and adhering the adhesive member supported by the support unit to the secondary battery cell.

Taping apparatus and method for secondary battery

The present invention relates to a battery cell sealing device for sealing a pouch of a battery cell, more particularly, to a battery cell sealing device configured to be capable of simultaneously sealing a plurality of battery cells accommodated in one chamber to be able to increase production or processing capacity of the battery cells in one chamber and accordingly, decrease cost of an entire equipment.

Battery cell sealing device

The present invention relates to an apparatus and a method of folding a pouch case of a battery cell, and more particularly, to an apparatus and a method of folding a pouch case of a battery cell capable of preventing a meandering in a folding process and reducing non-uniformity of a folding amount by forming a pre-folding line on a pouch wing and folding the pouch wing on the basis of the pre-folding line.

Apparatus and method of folding pouch case of battery cell

A pouch-type secondary battery includes an electrode assembly; and a pouch member comprising an internal space configured to accommodate the electrode assembly therein and a degassing sealing portion formed to project inwardly by sealing one end portion releasing internal gas.
