Abstract: An additive manufactured piston having a crown portion and a skirt portion form of an aluminum-cerium-silicon alloy. The piston includes a least one recess pocket in an unstressed region located at an interface between an inner surface of the crown portion and an outer surface of the skirt portion. The skirt portion includes an outer panel surface defining an external rib adjacent a peripheral end surface, at least one stiffening rib extending from a pin boss to a skirt end, and a wall thickness of between 0.2 mm and 1.0 mm in a region between the external rib and the at least one stiffening rib. The skirt portion further includes an internal first rib having a width W1 on a thrust side portion and an internal second rib having a width W2 located on an anti-thrust side portion, in which W1 is greater than W2.

Abstract: A battery cell stack assembly for a prismatic battery includes a plurality of monocells and two current collector bracket assemblies. Each monocell includes an anode electrode sheet having an outer perimeter and an anode cell tab and a cathode electrode sheet having a cathode cell tab. One of the current collector bracket assemblies electrically connect each of the anode cell tabs with one another and a remaining current collector bracket assembly electrically connects each of the cathode cell tabs with one another, and each current collect bracket assembly includes at least one arm that is positioned to electrically connect either two or more of the anode cell tabs or two or more of the cathode cell tabs to one another.
