Battery systems according to embodiments of the present technology may include a battery including a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The battery may define a recessed portion of the battery along the first surface of the battery between the first electrode terminal and the second electrode terminal. The battery systems may include a module electrically coupled with the battery. The module may include a circuit board. The module may include a first conductive tab extending from a second surface of the circuit board opposite the first surface of the circuit board. The first conductive tab may be electrically coupling the module with the first electrode terminal. The module may include a second conductive tab extending from the second surface of the circuit board. The second conductive tab may be electrically coupling the module with the second electrode terminal.

Non-rectangular metal batteries

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.

Battery cell with serpentine tab

Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the interior region of the housing. The set of electrodes may include a first electrode and a second electrode. The first electrode may include a tab coupled with a surface of the housing at a distal end and coupled with the first electrode at a proximal end. The tab may be coupled with a first surface of the first electrode. A first insulating material may be applied along a second surface of the first electrode across a section corresponding to a location where the tab is coupled with the first electrode. The batteries may also include a cap at least partially contained within the interior region of the housing. The cap may be characterized by a first surface facing the set of electrodes.

Rechargeable battery features and components

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.

Feedthroughs for thin battery cells

Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The housing may include a circumferential indentation proximate the first end. The housing may define a first interior region between the first end and the circumferential indentation, and the housing may define a second interior region between the circumferential indentation and the second end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the second interior region of the housing. The batteries may include a cap at least partially contained within the first interior region of the housing. The batteries may also include a first insulator positioned within the housing. The first insulator may extend across the circumferential indentation from the cap to the set of electrodes.

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.

The disclosed technology relates to an electrical feedthrough for a battery cell. The electrical feedthrough may include a rivet, an outer gasket, an inner gasket, a terminal and an insulator. The rivet compresses the outer gasket, inner gasket, and terminal to create a hermetic seal at an opening through an enclosure of the battery cell. The inner gasket includes a recessed portion for seating of the terminal to prevent rotation of the terminal with respect to the inner gasket, a protrusion for engaging a corresponding notch on the terminal to further prevent rotation of the terminal with respect to the inner gasket, and a mating surface for attaching to the insulator to align and position the insulator within the enclosure. The insulator is positioned between the battery cell and the inner gasket to prevent physical and electrical contact between the set of layers and the feedthrough.

Feedthrough with integrated insulator

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.

An electrosurgical energy channel splitter apparatus includes a channel input a plurality of channel outputs, and a controller. The channel input is configured to receive electrosurgical energy from an electrosurgical energy source. Each channel output is configured to couple to a respective electrosurgical device. The controller is coupled to the channel input and the plurality of channel outputs. The controller is configured to selectively direct the electrosurgical energy from the channel input to one of the plurality of channel outputs.

Electrosurgical energy channel splitters and systems for delivering electrosurgical energy

The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.

Devices and methods for treatment of vascular aneurysms

The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In one embodiment, a system for treating an aneurysm is disclosed. The system comprises a catheter delivery system, an expandable foam configured to pass through the catheter delivery system, and a stent having a first end and a second end. The stent is configured to extend across the aneurysm. The expandable foam is configured to expand in the aneurysm when exposed to a fluid.
