Abstract
(EN)
The present invention relates to a secondary battery, a manufacturing method therefor, and a pressing block for manufacturing a secondary battery. A secondary battery manufacturing method according to the present invention comprises: a forming step of forming a pouch sheet having a reception part formed therein to receive an electrode assembly; a folding step of receiving the electrode assembly in the reception part and folding the pouch sheet with reference to a folding part such that the reception part is isolated from the outside, thereby forming a battery case; and an anti-wrinkle step of forming an anti-wrinkle bending part on the outer peripheral part of the folded pouch sheet in order to prevent a wrinkle from appearing on the outer peripheral part.

La présente invention concerne une batterie secondaire, son procédé de fabrication, et un bloc de pression permettant de fabriquer une batterie secondaire. Un procédé de fabrication de batterie secondaire selon la présente invention comprend : une étape de formation consistant à former une feuille de pochette dans laquelle est formée une partie de réception permettant de recevoir un ensemble électrode ; une étape de pliage consistant à recevoir l'ensemble électrode dans la partie de réception et à plier la feuille de pochette par rapport à une partie de pliage de telle sorte que la partie de réception est isolée de l'extérieur, ce qui permet de former un boîtier de batterie ; et une étape anti-plis consistant à former une partie de flexion anti-plis sur la partie périphérique externe de la feuille de pochette pliée afin d'éviter qu'un pli n'apparaisse sur la partie périphérique externe.
