  • Moisture barrier composite film of silicon nitride and fluorocarbon polymer and its use with an on-cell tester for an electrochemical cell
    Patent number: 5925479
    Abstract: A light transparent moisture barrier useful for preventing moisture from destroying the effectiveness of a moisture sensitive cell condition tester on an electrochemical cell, comprises a plurality of very thin layers of amorphous silicon nitride and a hydrophobic fluorocarbon polymer on a flexible, polymeric substrate. The layers are formed on the substrate by a deposition process such as sputtering. The thickness of any individual layer is less than one micron.
    Type: Grant
    Filed: August 5, 1996
    Date of Patent: July 20, 1999
    Assignee: Duracell, Inc.
    Inventors: Guang Wei, Jack Treger, Bryan Christopher Lagos
  • Light transparent multilayer moisture barrier for electrochemical celltester and cell employing same
    Patent number: 5681666
    Abstract: A light transparent moisture barrier useful for preventing moisture from destroying the effectiveness of a moisture sensitive cell condition tester on an electrochemical cell comprises a plurality of very thin; alternating layers of an inorganic material and an organic material on a flexible, polymeric substrate. The layers are not laminated, but are formed on the substrate by a deposition or coating process and the thickness of any layer is less than 5 microns.
