The low voltage circuit breaker (CID) operates at a minimum threshold internal gauge pressure, for example, in the range of about 4 kg / cm2 to about 9 kg / cm2. Preferably, the CID comprises a first conductive plate, and a second conductive plate in electrical communication with the first conductive plate, wherein electrical communication between the first conductive plate and the second conductive plate is achieved by the minimum threshold Value is interrupted at 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 the periphery of the first end of the frustum, and an essentially planar cap sealing the second end of the frustrum do. The first end has a larger diameter than the second end. More preferably, the second conductive plate is in electrical contact with the essentially planar cap through the weld. A battery, preferably a lithium-ion battery, includes the CID described above. The method of manufacturing the CID may include forming the first and second conductive plates described above; And welding the second conductive plate onto the first conductive plate while adjusting the temperature of the first conductive plate such that the temperature of the first conductive plate does not exceed the melting point of the surface of the first conductive plate facing the weld. |
