Title (EN) POUCH-TYPE SECONDARY BATTERY COMPRISING ELECTRODE LEAD USING CONDUCTIVE POLYMER
(FR) BATTERIE SECONDAIRE DE TYPE POCHE COMPRENANT UN FIL D'ÉLECTRODE UTILISANT UN POLYMÈRE CONDUCTEUR

Abstract:
(EN) The present invention relates to a secondary battery comprising an electrode lead using a conductive polymer for shorting the electrode lead in order to maintain battery safety from overcharging or volume expansion such as swelling, etc. due to gas generated in an abnormal state of a pouch-type battery cell. The present invention has an effect of preventing currents from flowing into the pouch-type secondary battery in an overcharged state as well as in an abnormal state and an effect of excluding the lowering of energy density when a complicated apparatus is carried out in addition to the pouch-type secondary battery.
(FR) La présente invention concerne une batterie secondaire comprenant un fil d'électrode utilisant un polymère conducteur pour court-circuiter le fil d'électrode afin de maintenir la sécurité de la batterie vis-à-vis d'une surcharge ou d'une expansion de volume telle qu'un gonflement, etc. du fait du gaz généré dans un état anormal d'une cellule de batterie de type poche. La présente invention a pour effet de prévenir l'écoulement de courants dans la batterie secondaire de type poche dans un état surchargé ainsi que dans un état anormal et d'exclure l'abaissement de la densité d'énergie lorsqu'un appareil compliqué est réalisé en plus de la batterie secondaire de type poche.
(KO) 본 발명은 파우치형 전지셀의 비정상 상태에서 발생한 가스로 인한 스웰링 등의 부피 팽창 또는 과충전에 따른 전지 안전성을 유지하기 위하여 전극리드를 단락시키기 위한 전도성 폴리머를 이용한 전극리드를 포함하는 이차전지에 관한 것에 과충전뿐만 아니라 비정상 상태에서 발생하여 더 이상 파우치형 이차전지에 전류가 흐르는 것을 막을 수 있는 효과 및 파우치형 이차전지에 추가로 복잡한 장치를 진행할 경우, 에너지 밀도가 낮아지는 것을 배제할 수 있는 효과가 있다.
