Abstract
A secondary battery includes a protection module package including a tab bridge, an input/output terminal, and an insulating body that includes a middle block and side block, the middle block having the input/output terminal therein, the side block being spaced apart from the middle block, and the tab bridge connecting the middle block to the side block; and a bare cell including an electrode that is electrically connected to the tab bridge.
Claims32
A secondary battery, comprising:
- a protection module package including a tab bridge, an input/output terminal, and an insulating body that includes a middle block and side block, wherein the side block includes first and second side blocks that are respectively spaced apart from the middle block on a first side of the middle block and on a second side of the middle block that is opposite the first side, the middle block having the input/output terminal therein, the first and second side blocks being spaced apart from the middle block, and the tab bridge being formed of a different material from the insulating body, and the tab bridge including a first tab bridge connecting the middle block to the first side block, and a second tab bridge connecting the middle block to the second side block;
- and
- the secondary battery including a bare cell, including electrodes having different polarities, the first and second tab bridges being electrically connected to respective electrodes of the bare cell.
A secondary battery, comprising:
- a protection module package including a tab bridge, an input/output terminal, and an insulating body that includes a middle block and side block, the middle block having the input/output terminal therein, the side block being spaced apart from the middle block, and the tab bridge connecting the middle block to the side block;
- and
- a bare cell including an electrode that is electrically connected to the tab bridge,
- wherein:
- the insulating body includes an upper surface with the input/output terminal thereon, a lower surface disposed opposite the upper surface, and a side surface connecting the upper surface to the lower surface and forming a circumference of the insulating body, and
- the tab bridge includes:
- a fixing piece extending across the insulating body between the upper surface and the lower surface of the insulating body;
- and
- a connection piece that is bent from the fixing piece, the connection piece being connected to the electrode across the side surface of the insulating body.
