Abstract: A charging voltage of a battery may be determined based on an age of the battery. The age and charging voltage can be determined by a computing apparatus or a battery management system. The determined charging voltage may increase as the age of the battery increases. The battery may be charged at the charging voltage for the duration of a charge cycle. The battery may be charged using a charger.

Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: 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.

Abstract: Separator and electrolyte composites include a porous self-supporting separator film between or adjacent one or two electrolyte films. The electrolyte films may contain a glyme or mixture of glymes, LiX salt and complexing agent, such as PEO. The porous self-supporting separator film may be used dry or wetted with a liquid electrolyte composition. Solid state batteries and electrochemical cells are disclosed that include the described separator and electrolyte composites in combination with an anode and a cathode.

Abstract: A lithium-ion battery includes multiple electrodes. At least one of the electrodes is comprised of multiple sheets of electrode mixture, and each of the sheets includes a different percentage of a solid-state electrolyte within the electrode mixture. The sheets are laminated together and to a current collector such that a bottom sheet nearest the current collector comprises a lowest percentage of the solid-state electrolyte. A gradient of percentages of the solid-state electrolyte is formed from the bottom sheet to a topmost sheet comprised of a highest percentage of the solid-state electrolyte.
