Abstract:
The present invention provides an electrically conductive element for an electrochemical cell element having enhanced protection for an underlying metal substrate with a surface susceptible to forming metal oxides. One or more regions of the surface are coated with a metal coating overlaid with an adhesion promoting coating comprising a silicon containing material derived from organosilanes. The adhesion promoting coating is overlaid with a conductive, protective polymeric coating. The present invention further provides methods of making such an electrochemical cell element to have improved adhesion of conductive, protective polymer coatings.
