Abstract
A rechargeable battery includes an electrode assembly in a case, a terminal which passes through and protrudes from a cap plate, and a current collector plate in the case. The current collector plate electrically connects the electrode assembly and the terminal portion. The current collector plate has a fuse area which includes a fuse hole having a substantially elongated shape with round sides oriented in a widthwise direction of the current collector plate.
Claims17
A rechargeable battery, comprising:
- an electrode assembly in a case;
- a terminal which passes through and protrudes from a cap plate;
- and
- a current collector plate in the case and electrically connecting the electrode assembly and the terminal, wherein the current collector plate includes a bent area, a terminal area, and a fuse area between the bent area and the terminal area, the fuse area including a fuse hole without corners passing through the current collector plate, the fuse hole having a substantially elongated shape with round sides, and being elongated in a first direction of the current collector plate and perpendicular to a second direction of the current collector plate, the second direction being a direction between the bent area and the terminal area.
