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.
