Rechargeable battery

摘要

A rechargeable battery includes an electrode assembly charging and discharging a current, a case in which the electrode assembly is installed, a cap plate coupled to an opening of the case, an electrode terminal provided on the cap plate, and an external insulator receiving the electrode terminal from the outside of the cap plate. The electrode terminal includes a first plate terminal electrically connected to the electrode assembly, a second plate terminal separated from the first plate terminal, and a fuse portion connecting the first plate terminal and the second plate terminal.
