Title (EN) POUCH-TYPE SECONDARY BATTERY INCLUDING SEALING PART HAVING RECESS
(FR) BATTERIE RECHARGEABLE DE TYPE POCHETTE COMPRENANT UNE PARTIE D’ÉTANCHÉITÉ À ÉVIDEMENT
(KO) 실링부에 홈을 포함하고 있는 파우치형 이차전지
Abstract: front page image
(EN)As described above, the present invention provides a battery cell in which an electrode assembly having an anode/separation membrane/cathode structure is sealed together with an electrolyte solution in an electrode assembly receiving part of a pouch-type battery case. The battery case has thermally fused sealing parts formed on the outer peripheral surface thereof in a state in which the electrode assembly and the electrolyte solution are included therein. In order to prevent the sealing parts of the battery case from being corrugated when the battery cell is bent, both the side sealing parts, adjacent to the upper and/or lower sealing part where electrode terminals are located, have one or more indentation recesses formed in a direction from end portions thereof to a vertical central axis of the battery cell, and the areas of the side sealing parts where the indentation recesses are located are sealed at a higher sealing temperature than the remaining areas of the side sealing part.
(FR)La présente invention concerne un élément de batterie dans lequel un ensemble électrode présentant une structure anode/membrane de séparation/cathode est hermétiquement scellée conjointement avec une solution électrolytique dans une partie de réception d'ensemble électrode d'un boîtier de batterie de type pochette. Le boîtier de batterie comporte des parties d'étanchéité thermosoudées formées sur sa surface périphérique externe dans un état dans lequel sont compris en son sein l'ensemble électrode et la solution électrolytique. En vue d'empêcher l'ondulation des parties d'étanchéité du boîtier de batterie lorsque l'élément de batterie est plié, les deux parties d'étanchéité latérales, adjacentes à la partie d'étanchéité supérieure et/ou inférieure où des bornes d'électrode sont situées, comportent un ou plusieurs évidements à indentation formés dans une direction à partir de ses parties d'extrémité vers un axe central vertical de l'élément de batterie, et les zones des parties d'étanchéité latérales où les évidements à indentation sont situés sont hermétiquement scellées à une température d'étanchéité plus élevée que les zones restantes de la partie d'étanchéité latérale.
(KO)이상에서 설명한 바와 같이, 본 발명에 따른 전지셀은 양극/분리막/음극 구조의 전극조립체가 전해액과 함께 파우치형 전지케이스의 전극조립체 수납부 내에 밀봉되어 있는 전지셀로서, 상기 전지케이스는 전극조립체 및 전해액을 내장한 상태에서 외주면에 열융착한 실링부가 형성되어 있으며, 전지셀을 구부렸을 때 상기 전지케이스 실링부의 주름 발생을 방지할 수 있도록, 전극 단자들이 위치한 상단 및/또는 하단 실링부에 인접한 양 측면 실링부들에는 측면 실링부의 단부로부터 전지셀의 상하 중심축 방향으로 만입 홈이 1개 이상 형성되어 있고, 상기 만입 홈이 위치한 측면 실링부 영역은 측면 실링부의 나머지 영역보다 상대적으로 높은 실링 온도로 실링되는 것을 특징으로 하는 전지셀을 제공한다.
