Appl. No.:

13/567784

International Classification:

H01H 37/76

US Classification:

337186

Abstract:

A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever with electrical connection without dragging the sensing element.

International Classification:

H01M 50/172
H01M 50/531
H01M 50/543

Abstract:

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.

International Classification:

H01M 2/04
H01M 10/0585

Abstract:

Batteries according to embodiments of the present technology may include an electrode stack including a separator positioned between an anode and a cathode. The batteries may include an electrolyte. The batteries may include an enclosure extending about the electrode stack and containing the electrolyte. The enclosure may include a rigid housing defining a volume in which the electrode stack and the electrolyte are contained. The rigid housing may define a flange extending about the rigid housing. The enclosure may include a lid extending across the rigid housing. The lid may be characterized by a length and a width, and the lid may define a protrusion extending beyond the length or width on a side of the lid at a location corresponding to a predetermined strain location.

Abstract:

An electronic device includes an enclosure having a transparent cover defining a touch-sensitive surface, a display positioned within the enclosure and below the transparent cover, and a haptic device configured to produce a haptic output along the touch-sensitive surface. The haptic device may include a battery element electrically coupled to the display, a magnetic element, and a coil assembly fixed with respect to the enclosure and configured to induce an oscillatory movement of the battery element parallel to the display to produce the haptic output. In other examples, the coil assembly may be coupled to the battery element and the first and second magnetic elements may be fixed with respect to the enclosure.

Abstract:

The disclosed technology relates to an electrical feedthrough for a battery cell. The electrical feedthrough may include a pin configured to form an external battery terminal, an insulator surrounding the pin and configured to electrically isolate the pin, a channel, and a serpentine tab electrically coupled to the pin at a first end. The serpentine tab is nested within the channel to minimize use of space within an enclosure of the battery cell thereby increasing energy capacity of the battery cell by eliminating the need to allot space within the enclosure to accommodate the tab.
