Abstract
A current collector for a battery in an implantable medical device is presented. The current collector comprises a layer which includes a first surface and a second surface. For a cathode electrode plate, the layer possesses a lower resistivity of less than or about 2.7 Ohm meters (Ω)×108. For an anode electrode plate, the layer possesses a resistivity of about 2.5 Ω×108 to about 7 Ωm×108.
