Abstract: Battery packs including electrochemical cells and having a thermal radiation control surface treatment to modify radiative transfer of thermal energy into and from the electrochemical cell are provided herein. More specifically, battery packs including a pack enclosure, an electrochemical cell disposed within the pack enclosure, and a thermal radiation control surface treatment on an exterior surface of the electrochemical cell, an interior surface of the pack enclosure, or both, are provided herein.

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: An electrochemical cell includes a positive electrode including a first current collector, one or more first tabs, and a first active material. A negative electrode includes a second current collector, one or more second tabs, and a second active material. A separator is disposed between the positive electrode and the negative electrode. A resistive coating is configured to at least partially coat one or both of the first current collector, the second current collector, the one or more first tabs, and the one or more second tabs.

Abstract: An electrochemical cell comprising a first electrode separated from a second electrode by a shutdown separator. The first electrode can comprise a first current collector substrate having a first active material composite layered thereon. The second electrode can comprise a second current collector substrate parallel to the first current collector substrate. The second current collector substrate can have a second active material composite layered thereon. The first current collector substrate can have a first current collector tab extending from the first current collector substrate at a position along an axis parallel to a plane defined by the first current collector substrate. The second current collector substrate can have a second current collector tab extending from the second current collector substrate at a same position along the axis as the first current collector tab. A battery including the electrochemical cell and methods for manufacturing the battery are also described.
