  • Patent number: 10535860
    Abstract: A nonaqueous electrolyte secondary battery includes a conductive outer can, an electrode body in the outer can, a conductive seal plate tightly closing an open end of the outer can, and a cathode external terminal on the seal plate. The battery further includes a current cutoff mechanism (CID). The CID is located on the electrical conduction pathway between the cathode external terminal and the electrode body and interrupts the electrical coupling therebetween in response to an increased internal pressure in the battery. The CID includes a thin portion of the seal plate and a diaphragm. The diaphragm deforms to interrupt the electrical coupling between the cathode external terminal and the electrode body in response to the increase in the internal pressure in the battery. A cathode collector lead electrically couples the electrode body and the seal plate, and the seal plate connects the diaphragm and the cathode collector lead.

  • Patent number: 8628879
    Abstract: Magnetic Resonance (MR) conditional medical equipment for use in MR environments. The MR conditional medical equipment includes MR conditional handheld battery operated devices, for example, laryngoscopes, flashlights, and the like, and MR conditional carbon zinc power packs for operating the devices. The devices can be designed to be inoperable by standard alkaline batteries which would render the medical equipment non MR conditional. Alternatively, the devices can have a sealed power pack compartment pre-installed with a non-replaceable carbon zinc power pack.
