Abstract: A method for manufacturing a current collector for an electrode of a battery cell includes forming the current collector using a metal 3D printing process; defining L layers of the current collector, where L is an integer greater than zero during the 3D printing of the current collector; and defining a lattice structure in at least one of the L layers of the current collector during the 3D printing of the current collector.
