  • Method for providing a one-piece header assembly for hermetic battery terminal feedthrough, fill and closure designs
    Patent number: 7128765
    Abstract: An electrochemical cell having plate electrodes housed inside mating “clam shell” casing components. is described. When mated together, the casing components are form fitting with respect to the internal battery structure so as to reduce the overall size of the electrochemical package. A one-piece header containing both a glass-to-metal seal opening for a terminal lead and an electrolyte fill opening is used in conjunction with the clam shell casing.
    Type: Grant
    Filed: August 13, 2003
    Date of Patent: October 31, 2006
    Assignee: Wilson Greatbatch Technologies, Inc.
    Inventors: William Paulot, Dominick Frustaci, Kenneth Grubb, Harvey Hornung, II
  • Mismatched compression glass-to-metal seal
    Patent number: 6759163
    Abstract: A reverse mismatched compression glass-to-metal seal is described. In this seal, the coefficient of thermal expansion of the insulating glass is lower than that of the terminal lead and, the ferrule or casing body has a similar or higher coefficient of thermal expansion than that of the terminal lead.

  • Electrochemical cell with novel header assembly
    Patent number: 6569562
    Abstract: alkali metal electrochemical cell capable of discharge at elevated pressure and temperature is described. To help increase the cell's pressure tolerance, the cell header has an internal groove surrounding the glass-to-metal seal.
