    摘要: A battery comprises a first terminal in electrical communication with a first electrode of the battery, a second terminal in electrical communication with a second electrode of the battery, a battery can electrically insulated from the first terminal, and at least one current interrupt device in electrical communication with the battery can. The battery can includes a cell casing and a lid which are in electrical communication with each other. At least a portion of the battery can is at least a component of the second terminal, or is electrically connected to the second terminal. The current interrupt device includes a first conductive plate in electrical communication with the second electrode, and a second conductive plate in electrical communication with the first conductive plate. The second conductive plate separates from the first conductive plate when pressure inside the battery is greater than a predetermined value, whereby a current flow between the second electrode and the second terminal is interrupted.

    摘要: A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure. Preferably, the CID includes a first conductive plate and a second conductive plate in electrical communication with the first conductive plate, the electrical communication between the first and the second conductive plates being interrupted at the minimal threshold internal gauge pressure. The first conductive plate can include a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end, and the second conductive plate is in electrical contact with the essentially planar cap through a weld.

    摘要: A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure in a range of, for example, between about 4 kg/cm2 and about 9 kg/cm2. Preferably, the CID includes a first conductive plate and a second conductive plate in electrical communication with the first conductive plate, the electrical communication between the first and the second conductive plates being interrupted at the minimal threshold internal gauge pressure. More preferably, the first conductive plate includes a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end. More preferably, the second conductive plate is in electrical contact with the essentially planar cap through a weld. A battery, preferably a lithium-ion battery, comprises a CID as described above. A method of manufacturing such a CID comprises forming first and second conductive plates as described above, and welding the second conductive plate onto the first conductive plate while a temperature of the first conductive plate is controlled so as not to exceed the melting point of a surface of the first conductive plate opposite the weld.
