    • PURPOSE: A secondary battery is provided to maintain performance of a battery in case external impact such as dropping, etc and to effectively prevent internal short of a tap-lead joint by an electrically insulative thermal contraction tube protecting the tap-lead joint. CONSTITUTION: A secondary battery comprises an electrode assembly of a positive electrode/separator/negative electrode in a battery case of a laminate sheet which comprises a resin layer and a metal layer. The electrode taps(301,302) are combined with electrode leads(400,410) and protruded to outside. A heat-shrinkable tube(510) surrounds joints(401,411) of the electrode tap and electrode lead. The electrode assembly is a stack type electrode assembly laminated in a state that a separator is inserted between a plurality of positive electrodes and negative electrodes. The tap-lead joint consists of a structure that a plurality of electrode taps are welded and combined to one electrode lead.
    • 目的:提供二次电池以在外部冲击(如跌落等)的情况下保持电池的性能,并通过保护接头引线接头的电绝缘热收缩管有效地防止引线接头内部短路。 构成:二次电池包括在包含树脂层和金属层的层叠片的电池壳体中的正极/隔板/负极的电极组件。 电极抽头(301,302)与电极引线(400,410)组合并突出到外部。 热收缩管(510)围绕电极丝和电极引线的接头(401,411)。 电极组件是以分隔件插入在多个正极和负极之间的状态层叠的叠层型电极组件。 抽头接头由多个电极接头焊接并组合成一个电极引线的结构组成。
