Abstract: Battery core packs employing minimum cell-face pressure containment devices and methods are disclosed for minimizing dendrite growth and increasing cycle life of metal and metal-ion battery cells.

Abstract: Alkali metal secondary batteries that include anodes constructed from alkali metal foil applied to only one side of a porous current collector metal foil. Openings in the porous current collectors permit alkali metal accessibility on both sides of the anode structure. Such anode constructions enable the utilization of lower-cost and more commonly available alkali metal foil thickness, while still achieving high cell cycle life at a significantly reduced cost. Aspects of the present disclosure also include batteries with porous current collectors having increased volumetric and gravimetric energy densities, and methods of manufacturing anodes with porous current collectors.

Abstract: A method of forming anodes for electrochemical devices by laminating a metal foil to a current collector and creating anode-active-material patches, composed of the metal foil, that are spaced from one another by inter-patch regions, wherein each inter-patch region provides a location for forming one or more electrical tabs of the finished anodes. The method can further include applying conductive-coating patches to the current collector prior to laminating the metal foil to the current collector, wherein each conductive-coating patch corresponds to one of the anode-active-material patches. In some embodiments, the conductive-coating patches can assist with forming the anode-active-material patches and/or can improve the cycling performance of an electrochemical device made using anodes made therewith. Anodes containing anode-active material and conductive coatings applied to current collectors are also disclosed.

Abstract: Anode subassembly sheets that include a lithium-metal layer sandwiched between a pair of separator layers to ease handling of the lithium metal to promote fast and efficient stacked-jellyroll assembly. In some embodiments, the separator layers are pressure laminated to the lithium-metal layer without any bonding agent. In some embodiments, a stacked jellyroll is made by alternatingly stacking anode subassembly sheets with cathode sheets. In some embodiments, a functional coating beneficial to the lithium-metal layer is provided to one or more separator layers prior to laminating the separator(s) to the lithium metal layer. Lithium-metal batteries made using stacked jellyrolls made in accordance with aspects of the disclosure are also described.
