Abstract
A method for forming a current collector is provided. At least two carbon nanostructure reinforced copper composite substrates are provided. The at least two carbon nanostructure reinforced copper composite substrates are stacked to form a composite substrate. An active metal layer is disposed on a surface of the composite substrate to form a first a composite structure. The first composite structure is pressed to form a second composite structure. The second composite structure is annealed to form a third composite structure. The third composite structure is de-alloyed to form a porous copper composite.
