Abstract: Presented are silicon and other anodes and methods for producing same. In one aspect of the disclosure, a pristine anode material is prelithiated to produce a prelithiated anode substrate. Precursors are combined, such as using a flow into a deposition chamber, to produce a target chemical formulation formed as a hydrophobic and hermetic protective coating over the prelithiated Si-anode substrate. The result is a protected anode substrate. A laser may thereafter be used for further processing of the protected the protected anode substrate to form an anode. In other embodiments, a silicon oxide anode, a graphite anode, or a silicon-graphite blended anode is used.

Abstract: A lamination system is contemplated. The system may have a modular design configured to fabricate a laminate from an incoming material. The system may be configured to produce the laminate with an outer layer comprising the incoming material such that the resulting layer has a width greater than a width of the incoming material prior to lamination.

Abstract: A method for fabricating wide and continuous double-sided lithium metal anodes includes thermally evaporating lithium to form first and second continuous lithium layers on respective first and second continuous polymer substrates, so as to form respective first and second continuous lithium/polymer sheets. The first and second continuous lithium/polymer sheets are laminated onto respective top and bottom surfaces of a continuous metallic substrate, which may be made of copper, with the first and second continuous lithium layers being disposed in direct contact with the respective top and bottom surfaces to form a continuous polymer/lithium/metal/lithium/polymer structure. The first and second continuous polymer substrates are then removed from the continuous polymer/lithium/metal/lithium/polymer structure to provide a continuous lithium/metal/lithium anode structure.

Abstract: A method of forming edge materials on an electrochemical cell component having a metallic foil substrate including a conductive coating on top and bottom surfaces and first and second edge portions extending laterally outward beyond the conductive coating, includes pulling the metallic foil substrate from a roll, feeding the metallic foil substrate through a profile machine and forming notches within the first and second edge portions that extend inwardly from outermost edges of the first and second edge portions a distance less than a distance between the outermost edges and the conductive coating, and define a plurality of electrode tabs, feeding the strip of metallic foil substrate sequentially through a plurality of 3-dimensional printing machines and printing edge materials onto the electrode tabs and the first and second edge portions between the plurality of electrode tabs, and rolling the strip of metallic foil substrate onto a roll.

Abstract: A method for laminating a lithium metal anode is provided. The method includes procuring a current collector, including a portion of the current collector to be covered with a lithium foil lamination, and procuring a plurality of lithium foil portions. The plurality of lithium foil portions each include a length configured for matching one of a length of the portion of the current collector to be covered with the lithium foil lamination or a width of the portion of the current collector to be covered with the lithium foil lamination. The method further includes disposing the plurality of lithium foil portions upon the portion of the current collector to be covered with the lithium foil lamination, wherein the plurality of lithium foil portions is arranged side-by-side, and applying heat and pressure to join the plurality of lithium foil portions to the current collector.
