    Abstract: A method of making a lithium metal anode for a battery cell is disclosed. The method comprises providing a current collector 12 comprising metal and having a first side 14. The method further comprises applying a metal oxide layer to the first side 14 of the current collector 12. The metal oxide layer comprises metal oxide for enhanced wettability of the first side 14. The method further comprises loading molten lithium to the metal oxide layer at a set temperature in an inert atmosphere to define a molten lithium layer having a first thickness on the metal oxide layer. The method further comprises reducing the first thickness of the molten lithium layer to a second thickness at the set temperature in the inert atmosphere. The method further comprises cooling the molten lithium layer to solidify the molten lithium layer in the inert atmosphere, defining a solid lithium layer on the metal oxide layer.

    Abstract: A method of making a calendered electrode for a battery cell comprises introducing a coated electrode having a first surface extending thereover. The coated electrode has a predetermined density of active materials for ion transport. The method further comprises selectively modifying the coated electrode by patterning the first surface to define a patterned electrode having a first portion and a second portion. After the step of selectively modifying, the method further comprises compressing the patterned electrode by calendering the first surface to provide the first portion having a first density of active materials and the second portion having a second density of active materials. The second density is greater than the first density to define the calendered electrode having a spatial variation of active material density.

    Abstract: A thermal-management system, for use in controlling temperature of at least a first workpiece of multiple workpieces being joint. The thermal-management system includes a thermal sleeve sized and shaped to at least partially surround the first workpiece during operation of the thermal-management system. The thermal sleeve comprises a fluid compartment configured to hold heat-transfer fluid, such as nanofluid, for use in heating or cooling the first workpiece during operation of the thermal-management system. In various embodiments, the thermal-management system includes a fixture portion having an elongate channel for affecting temperature by way of heat-transfer fluid passed through the channel. In some embodiments, the thermal-management system includes a heat-transfer fluid bath body for holding heat-transfer fluid to cool or heat workpieces being welded together.

    Abstract: A releasable adhesive system for joining a first surface to a second surface. The system includes a primary material having a first portion including at least one first-portion molecule configured to be positioned parallel with at least one first-surface molecule of the first surface, and a second portion, opposite the first portion, including at least one second-portion molecule configured to be positioned parallel with at least second surfaced one molecule of the second surface. The first surface molecule, positioned parallel with the first-surface molecule, is configured to maintain bonds between the first portion and the first surface up to one or more pre-determined force scenarios, such as pre-determined shear, pull, and peel forces being exerted on the first surface. The second portion can function similarly with respect to the second surface. A method is also provided for joining the first surface to the second surface using such releasable adhesive.
