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.

Abstract: Low waste methods for three-dimensional printing techniques are provided. A method includes performing a preceding additive infusion process including: solubilizing an additive into a medium in a supercritical fluid state; contacting a preceding material with the medium to infuse a portion of the additive into the preceding material to form a preceding additive-infused material; and separating remaining additive from the medium. Further, the method includes performing at least one succeeding additive infusion process including: solubilizing the remaining additive and, optionally, additional additive, into the medium in a supercritical fluid state; and contacting a succeeding material with the medium to infuse at least a portion of the remaining and additional additive into the succeeding material to form a succeeding additive-infused material, wherein the medium from the preceding additive infusion process is reused in the at least one succeeding additive infusion process.
