Some examples include a lithium-ion battery including an electrode assembly, a battery case, and an insulator. The electrode assembly includes a plurality of stacked electrodes. The battery case includes a cover and a housing. The housing includes a bottom, a perimeter side, and an open top. The cover is configured to extend across the open top. The cover and the housing form an interior enclosure to house the electrode assemble with the cover and the housing sealingly coupled at the lip. The insulator includes a body and a profiled portion. The body being generally planar and the profiled portion extending from the body at an angle. The body is disposed between the electrode assembly and the cover of the battery case. The profiled portion extends between the electrode assembly and the lip of the housing. The insulator is to provide a barrier between the electrode assembly and the sealed lip.

Lithium-ion battery

Devices and methods disclosed herein relate to forming superior mechanical and electrical connections between stacks of foils such as those used in electrochemical cells. The connections described herein use multiple weld types and choice of materials to promote electrical and mechanical connectivity using separate weld types.

Shaped rechargeable battery electronic interconnect

In some examples, an assembly for a medical device. The assembly includes a first electrode comprising a first conductive tab, and a first current collector; a second electrode including a second conductive tab, a second current collector, a third current collector, and at least one connector connecting the second current collector to the third current collector, wherein the second current collector and the third current collector are folded over each other about the at least one connector, wherein the second conductive tab is coupled to the second current collector, and wherein the third current collector is electrically coupled to second conductive tab via the at least one connector and the second current collector; and a foil package being sealed over the first conductive tab and the second conductive tab to partially enclose the first electrode and second electrode.

Battery assembly

Medical devices include a separate enclosure that houses a battery and electrically isolates the battery from external conditions such as any metal enclosures and ultimately isolates the battery from body fluids. Thus, the separate enclosure attaches to a housing of a medical device and provides for modularity of the battery which allows, for instance, different size batteries to be used with the same medical device design. The separate enclosure further prevents stimulation current from leaking back to the battery housing by providing the electrical isolation.

Implantable medical devices with electrically isolated batteries in a separate enclosure

Some examples include an electrode for an electrochemical cell including a plate portion and a tab portion. The plate portion includes a plate body, a perimeter body edge, and an inset area recessed into the plate body from the perimeter body edge. The inset area is defined by an inset edge. The tab portion extends from the plate portion. The tab portion includes a tab body and tab body edge. The inset edge extends between the perimeter body edge and the tab body edge.

Electrode

Various embodiments of a battery assembly include a first housing shell, a second housing shell, an insulator and battery components. The first housing shell has a first perimeter side wall, a first housing bottom, and a first contact area on the first housing bottom. The second housing shell has a second perimeter side wall, a second housing bottom, and a second contact area on the second housing bottom. The second housing shell is disposed in the first housing shell with the second contact area opposing the first contact area. The insulator is interposed between the first housing shell and the second housing shell to effect electrical insulation between the first housing shell and the second housing shell. The battery components include an anode electrode, a cathode electrode, and a separator interposed between the cathode electrode and the anode electrode. The separator contains an electrolyte.

Battery encasement for implantable devices

A battery terminal for an implantable battery is described. The battery terminal includes a foil stack, first and second side elements, and a weld joint coupling the foil stack and the side elements. The side elements define a varying height profile and a greatest height adjacent an inner surface of the side element in contact with the foil stack. Each element may define a height profile along the width that tapers toward an outer surface, biasing mass of the element close to the foil stack.

Power terminal for implantable devices

An inertial measurement unit (IMU) is provided that includes a container that defines a cavity. A sensor suit or ISA having a housing is provided in the container of the IMU. A dampening material is provided between the housing of the ISA and the container of the IMU. The dampening material may be applied by coating, spraying, or dipping, or may be separately molded and then inserted, if desired. A sway space may also be provided between the ISA and the IMU container.
