Abstract
The present invention provides electrodes comprising a current collector in the form of an augmented metallic foil having a fine and uniform corrugation that augments the functional porosity of the foil. The presently disclosed electrodes having augmented metallic foil, exhibiting high functional porosity, as current collectors are useful in many application, including, but not limited to lithium-ion barratries and electric devices using the same for energy.
