Title
(JA) パウチ型二次電池
Abstract
(JA)

前記課題を解決するための本発明の実施例によるパウチ型二次電池は、正極及び負極を含む電極と、分離膜が積層される電極組立体;前記電極組立体を収容するパウチ型の電池ケース;前記電極と連結され、 前記電極組立体の一側から突出される電極タブ;一端が前記電極タブと連結される第1電極リード;一端が前記第1電極リードの他端と連結され、他端が前記電池ケースの外部に突出される第2電極リード;及び前記第1電極リード及び前記第2電極リードを互いに接着させて連結する連結部;を含むが、前記第1及び第2電極リードのうち少なくとも一つには、前記連結部を介して互いに接着される接着面に少なくとも一つのノッチが形成される。
