A rechargeable battery includes an electrode assembly including a first electrode, a second electrode, and a separator between the first and second electrodes; a case housing the electrode assembly; and a cap assembly connected to the case. The cap assembly includes a first tab electrically connected to the first electrode, a second tab electrically connected to the second electrode, an deformable plate capable of electrically connecting the first tab and the second tab by being deformed due to a pressure increase, and an intermediate member formed between the first tab and the deformable plate.
摘要:
A rechargeable battery according to an exemplary embodiment of the present invention includes an electrode assembly, a case containing the electrode assembly, and a cap assembly. The electrode assembly includes a first electrode, a second electrode, and a separator between the first and second electrodes. The cap assembly is coupled to the case. The cap assembly includes a tab that is electrically connected to the first electrode and a deformable plate that is electrically connected to the second electrode. The deformable plate also includes a notch that is opened due to an increase of pressure. The deformable plate deforms as a result of increased pressure and electrically contacts the first tab, short circuiting the rechargeable battery.
摘要:
A rechargeable battery with overcharging protection. According to an embodiment of the present invention, 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 said 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.
