摘要： The disclosed technology relates to electrical feedthroughs for thin battery cells. A battery cell enclosure includes a terraced portion having a reduced thickness relative to another portion of the enclosure. The enclosure includes an opening disposed on a horizontal surface of the terraced portion for receiving the electrical feedthrough. Because the feedthrough is disposed on the horizontal surface of the terraced portion, the feedthrough may be over-sized thereby reducing the resistance and impedance of the feedthrough without increasing the height or thickness of the enclosure.

摘要： The disclosed technology relates to an electrical feedthrough for a cylindrical battery cell. The electrical feedthrough may include an annular channel having an outer sidewall, an inner sidewall, and a base; an insulator formed of glass having an overmold portion; and a pin extending through the insulator and configured to form an external battery terminal. The insulator is bonded to the inner sidewall of the annular channel and a portion of the base of the annular channel. The overmold portion prevents electrical contact between a set of electrodes and the electrode feedthrough.

摘要： Electrical feedthroughs are presented for redistributing thermally-induced stresses that result from welding. In some embodiments, an electrical feedthrough includes a tubular conduit having a flange at one end. The flange includes a first surface disposed opposite a second surface. The first surface includes at least one of a protrusion and a notch. The electrical feedthrough also includes an electrically-conductive terminal disposed through the tubular conduit. An electrically-insulating material is disposed between the tubular conduit and the electrically-conductive terminal and forms a seal therebetween. The protrusion and the notch are configured individually or as a combination to reduce thermally-induced stresses within the electrically-insulating material that result from welding the flange. Methods for welding such electrical feedthroughs to a wall, such as a wall of a battery housing, are also presented.

摘要： A first electronic device is positionable between one or more contact positions and an aligned position with respect to a second electronic device. One or more actuators of the first electronic device are activated in response to one or more sensors of the first electronic device determining that the first electronic device and second electronic device are misaligned. Activation of the actuator may result in the first electronic device moving to the aligned position. In some implementations, the actuator may move the first electronic device toward the aligned position when activated. In other implementations, the actuator may overcome static friction to put the first electronic device in motion when activated and when the first electronic device is in motion one or more alignment mechanisms may overcome the kinetic friction to move the first electronic device to the aligned position.

摘要： Electrical feedthroughs are presented that are integrated within a wall of a battery housing. In some embodiments, an electrical feedthrough includes a battery housing defining an opening. The electrical feedthrough also includes a collar disposed around the opening and forming a single body with the wall. The electrical feedthrough also includes an electrically-conductive terminal disposed through the collar. The electrical feedthrough additionally includes an electrically-insulating material disposed between the collar and the electrically-conductive terminal and forming a seal therebetween. In some embodiments, the wall has a thickness equal to or less than 1 mm. In some embodiments, the collar protrudes into the battery housing. In other embodiments, the collar protrudes out of the battery housing. In some embodiments, a cross-sectional area of the electrically-conductive terminal is at least 40% of an area bounded by an outer perimeter of the collar. Batteries incorporating the electrical feedthroughs are also presented.

摘要： Aspects of the present disclosure involve various battery can designs. In general, the battery can design includes two fitted surfaces oriented opposite each other and seam welded together to form an enclosure in which a battery stack is located. To form the enclosure, the two fitted surfaces are welded together along the large perimeter. Other swelling-resisting advantages may also be achieved utilizing the battery can design described herein including, but not limited to, the ability to modify one or more can wall thicknesses to control a pressure applied to the battery stack by the can, overall reduction in wall thickness of the can through the use of stronger materials for the can surfaces, additional supports structures included within the can design, and/or bossing or other localized thinning of surfaces of the can.
