    • A secondary battery including: a battery unit including a battery cell and a lead tab that protrudes from the battery cell; a frame case for supporting the battery unit and including a first support portion for supporting the battery cell and a second support portion for supporting the lead tab; and a connection member for perforating a connection hole formed in the lead tab and extending in a direction of the second support unit, wherein the connection hole of the lead tab includes: a first connection hole that is spaced apart from a first edge of the lead tab by a first width; and a second connection hole that is spaced apart from a second edge of the lead tab by a second width. The secondary battery may reduce electrical resistance of a charge/discharge path and has improved efficiency.
    • 一种二次电池,包括:电池单元,其包括从所述电池单元突出的电池单元和引线片; 用于支撑电池单元并包括用于支撑电池单元的第一支撑部分和用于支撑引线片的第二支撑部分的框架壳体; 以及连接构件,用于对形成在所述引线片中并沿所述第二支撑单元的方向延伸的连接孔进行穿孔,其中所述引线片的所述连接孔包括:与所述引线的第一边缘间隔开的第一连接孔 标签以第一宽度; 以及第二连接孔,其与所述引线片的第二边缘间隔开第二宽度。 二次电池可以降低充电/放电路径的电阻并且提高效率。
