    • Provided is a battery pack, which has excellent structural stability against external shocks and superior binding force of a battery cell to a frame member, is easily finished, and is reduced in thickness and width. The battery pack(100) comprises: a battery cell(200) in which an electrode assembly is accommodated in a laminate type sheet case(210) comprising resin layers and metal layers and is sealed; a top and bottom open frame member(300) which is fitted with the battery cell(200); and an external film(400) which is wrapped round the external surface of the battery cell(200) fitted in the frame member(300). Fastening grooves into which side sealing parts(230) of the battery cell(200) are vertically bended and inserted, are formed at upper ends or lower ends of both side frames(320,330) of the frame member(300).
    • 本发明提供了一种电池组,其具有优异的抗外部冲击的结构稳定性和电池单元对框架构件的优异的结合力,容易完成,并且其厚度和宽度减小。 电池组(100)包括:电池组(200),其中电极组件被容纳在包括树脂层和金属层的层叠型片盒(210)中并被密封; 安装有电池单元(200)的顶部和底部开放框架构件(300); 以及缠绕在装配在框架构件(300)中的电池单元(200)的外表面的外部膜(400)。 在框架构件(300)的两个侧框架(320,330)的上端或下端形成有将电池单元(200)的侧面密封部(230)垂直弯曲和插入的紧固槽。
