A rechargeable battery comprising:
- an electrode assembly;
- a cell body configured to receive the electrode assembly;
- a pouch comprising:
- a sealing portion at a first side surface of the cell body formed by sealing an outer portion thereof, and
- a terrace configured to draw out a first lead tab and a second lead tab connected to the electrode assembly at a second side surface of the cell body, wherein the terrace includes:
- a bottom portion connected to a bottom of the cell body, and
- a side wall portion bent at the bottom portion and connected to the sealing portion;
- and
- an insulation tape insulating the sealing portion from the cell body and including a short circuit check hole adjacent to an end of the terrace, wherein the short circuit check hole at least partially exposes a side end of the sealing portion and a side end of the terrace,
