Abstract: A battery includes a separator having a first side and a second side opposing the first side. The battery also includes an anode having an anode face that faces the first side of the separator, where the anode face includes an anode face surface area. The battery also includes a cathode having a cathode face that faces the second side of the separator, where the cathode face includes a cathode face surface area. A surface area ratio between the anode face surface area and the cathode face surface area is between 1.030 and 1.038.

Abstract: A housing of a battery may be produced to have a reduced flange, such that an interior volume of the housing is increased. The housing may include a can and a cover welded to one another to form a flange of the housing. The cover may be generally planar, and the can may include a curved portion and a planar portion extending from the curved portion. The planar portion may be welded to the cover to form the flange. A weld seam between the can and the cover may begin generally at an end of the planar portion of the can adjacent to the curved portion, and the flange may be cut along or adjacent to the weld seam. In particular, a distance between a transition point of the curved portion of the can and an outermost end of the flange may be less than 300 microns.

Abstract: Methods and structures for manufacturing and assembling matching parts in a manufacturing line are described. In some embodiments, the parts are portions of a consumer product, such as an electronic device. The matching parts are manufactured and assembled in a way such that the interface between the matching parts is substantially seamless. In some embodiments, the interface has a feature with curved portions. Methods involve measuring the dimensions of a primary part and custom machining a secondary part to seamlessly fit with the primary part. In this way, the secondary part is made to uniquely fit the primary part. The primary and secondary parts can be marked to identify them as matching parts in a manufacturing environment where numerous pairs of parts are made.

Abstract: The disclosed technology relates to manufacturing a battery cell. Manufacturing the battery cell can include applying a mask onto a first surface of a current collector, coating the first surface of the current collector with an active coating, removing the mask from the first surface of the current collector, stamping the current collector to form an anode layer with an uncoated tab, and arranging a stacked set of layers within an enclosure, such that the stacked set of layers comprise a cathode layer, the anode layer, and a separator layer disposed between the cathode layer and the anode layer.
