Abstract: A method for manufacturing a current collector for an electrode of a battery cell includes providing a wire mesh current collector including wires that have a diameter and form mesh junctions; and rolling the wire mesh current collector using a first roller and a second roller, wherein the first roller and the second roller are spaced by a predetermined gap. The predetermined gap is less than 2 times the diameter of the wires of the wire mesh current collector.
