  • Dissimilar Material Battery Enclosure for Improved Weld Structure
    Publication number: 20120282519
    Abstract: An electrochemical cell having an enclosure comprised of an enclosure body portion composed of a relatively high electrical resistivity material and an enclosure lid portion composed of a ductile material is discussed. The body portion of the enclosure preferably comprises Grade 5 or 23 titanium and the lid portion preferably comprises Grade 1 or 2 titanium. The enclosure lid is joined to the body of the enclosure through a welding process such as laser welding. The combination of these differing materials provides an enclosure that effectively retards the occurrence of eddy current induced heating as well as provides an enclosure that is more mechanically robust.

  • Method for coating noble metals on titanium current collectors for use in nonaqueous Li/CFcells
    Patent number: 8268466
    Abstract: A lithium/fluorinated carbon electrochemical cell having the CFx material supported on a titanium current collector screen sputter coated with a noble metal is described. The gold, iridium, palladium, platinum, rhodium and ruthenium-coated titanium current collector provides the cell with higher rate capability, even after exposure to high temperatures, in comparison to cells of a similar chemistry having the CFx contacted to a titanium current collector painted with a carbon coating.
