Current collectors for rechargeable batteries

Abstract

The present invention provides a foil with fine and uniform functional porosity that can be produced cheaply in roll-to-roll configuration, whereas the porosity stems from corrugation and/or perforation and of the foil. The presently disclosed augmented metallic foils are useful in many application, including, but not limited for use as current collectors in lithium-ion barratries.
