Abstract:
A rechargeable battery may include an electrode assembly that performs a charge and discharge action, a case in which the electrode assembly is inserted, a cap plate coupled to an opening of the case, and an electrode terminal in a terminal hole of the cap plate. The electrode terminal may include a plate terminal outside the cap plate and corresponding to the terminal hole, the plate terminal including a through-hole, a first groove, and a second groove, and a rivet terminal, the rivet terminal passing through the terminal hole, being inserted in the through-hole, and being riveted to the plate terminal at an upper end of the rivet terminal. The first groove may extend from the through-hole at an upper end side of the rivet terminal, and the second groove may extend from the first groove to an outer side of the plate terminal.

Abstract:
A rechargeable battery includes an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and the second electrode. The rechargeable battery also includes a case accommodating the electrode assembly. The rechargeable battery further includes a cap plate including a first plate and a second plate coupled to the first plate along a joint. The cap plate is coupled to an opening of the case. The rechargeable battery also includes a vent unit at the joint where the first plate of the cap plate is coupled to the second plate.
Abstract:
A battery module includes an electrode assembly in a case, at least one current collector in the case, the current collector being electrically connected to the electrode assembly, a cap plate covering the case, the cap plate including a safety vent and at least one terminal inserter penetrating the cap plate, at least one terminal part including a terminal plate outside the case and a connector connecting the at least one current collector to the terminal plate through the at least one terminal inserter, at least one fixing member fixing the terminal part into the cap plate, and a groove pattern in an area of the cap plate adjacent to the safety vent.
Abstract:
A rechargeable battery includes a case, a first electrode coupled to the case, a second electrode coupled to the case and the second electrode having a portion extending outside of the case, a short bar electrically coupled to the portion of the second electrode, and an extensible member extending from the case and at least a portion of the short bar being on the extensible member with a gap therebetween. The extensible member is configured to couple the short bar electrically to the first electrode in response to an overcharging condition of the rechargeable battery, thereby short-circuiting the first and second electrodes via the short bar.
