Abstract
A rechargeable battery including a bare cell with an electrode assembly having two electrodes and a separator, a case for storing the electrode assembly, a cap plate for covering an opening of the case, and a protection circuit module coupled with the cap assembly. A portion of the lower surface of the protection circuit module is formed of a synthetic resin, and contacts a region of the cap plate also formed of a synthetic resin. The protection circuit module and the cap plate an be coupled together by adhesion, welding or melting.
Claims19
