Angled, single laser weld and a method of forming an angled, single laser weld including arranging a first and second faying surfaces of a first and second component adjacently to form an interface between the components; irradiating at least one of the first and second components at the interface with a laser, wherein the first faying surface defines a plane formed at an angle alpha in the range of +/−5 degrees to 60 degrees from an axis A perpendicular to the first front surface and the second faying surface matches the first faying surface; and forming a junction at the interface with an hourglass shaped weld.

A method and associated device for joining a battery cell tab to a plurality of foils associated with a plurality of electrodes of a battery cell are described. This includes arranging the plurality of foils in a stack, and joining, via a first joining device, the plurality of foils, wherein the first joining device defines a joining region. A portion of the battery cell tab is arranged on the plurality of foils, and joined, via a second joining device, to the plurality of foils. The second joining device generates a weld joint that is encompassed within the joining region defined by the first joining device. In doing so, weld quality and strength of internal welds in a battery cell may be improved by reducing the occurrence of porosities and cracks in the foil/tab weld joints.
