ANODE ASSEMBLY FOR A BATTERY CELL CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. provisional application no.63/383,040, filed November 9, 2022, the entire contents of which are incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to an anode assembly for a battery cell and methods of forming the same. BACKGROUND [0003] Lithium (Li) metal is considered an ideal electrode (e.g., anode) material for next generation energy storage systems (e.g., batteries) due to its low reduction potential (-3.04 V as DOMPBQFE SO B RSBNEBQE IXEQOHFN FLFDSQOEF$ BNE IJHI RPFDJ[D DBPBDJSX #,0/) M3I(H$' 9OVFUFQ% lithium electrodes (e.g., anodes) have a tendency to form dendrites that may permeate between an anode and cathode, thereby creating short circuits.

Metal materials frequently disposed on the anode layer are sensitive to environmental conditions (e.g., moisture and oxygen). This sensitivity of the metal materials and the price associated with refining battery-grade metal materials increases costs for fabrication of the battery cells, since the manufacturing process must account for sourcing, storing, and handling of the metal materials. It is preferable to form a lithium-free anode, wherein the lithium metal which forms the anode active material is generated upon the first charge of the cell from lithium originally disposed in the cathode. [0005] As such, there remains a need to provide an improved anode assembly for a battery cell.

[0263] VI. EXAMPLES [0264] In order that the invention described herein may be more fully understood, the following examples are set forth. The examples described in this application are offered to illustrate the methods and anode assemblies provided herein and are not to be construed in any way as limiting their scope. [0265] Example 1: Silver/Nickel Anode Assembly [0266] A separator layer and an anode layer at least partially disposed on the separator layer and having a first surface facing the separator layer and a second surface facing away from the separator layer was provided. The separator layer and the anode layer measured 1 cm x 1 cm. The separator layer comprised a lithium lanthanum zirconium oxide (LLZO) solid-state electrolyte (SSE) material. The anode layer comprised a LLZO SSE material. The pores of the anode layer were substantially free of a metal material, such as lithium metal. [0267] The separator layer and the anode layer were placed into an apparatus with a 7.2 mm × 7.2 mm square window on the bottom. The separator layer and the anode layer were placed into the apparatus such that a deposited layer would be disposed on the anode layer by a line-of-sight, thermal evaporation process with a Metra thermal evaporator. The deposited layer was disposed only on the anode layer in the area of the 7.2 mm × 7.2 mm window, leaving a 1.4-mm border of the anode layer free of the deposited layer around the edge of the deposited layer. [0268] From a resting state under vacuum, an evaporation chamber of the thermal evaporator was vented to bring it to atmospheric pressure. One electrically conductive boat was loaded with silver pellets and another electrically conductive boat was loaded with nickel pellets. Each electrically conductive boat was then connected to electrical posts in the evaporation chamber. 44 49810322.1 The apparatus containing the separator layer and the anode layer was loaded into the evaporation chamber above the electrically conductive boats with the anode layer facing the boats. The chamber was then pumped down to less than 3 × 10 -6 Torr with a roughing pump and a turbo pump. The electrically conductive boat containing silver was heated by increasing the current passing through the boat until the silver melted. Once the silver melted, a shutter was opened that allowed the silver to evaporate and deposit on the anode layer. Once a desired thickness was achieved (~100 nm, as measured by the quartz crystal), the shutter was closed and the silver was cooled. After the silver was disposed on the anode layer, the boat containing nickel was heated by increasing the current until the nickel melted. Once the nickel melted, the shutter was again opened, allowing the nickel to evaporate and deposit on the silver that was previously deposited on the anode layer. Once the desired thickness was achieved (~400 nm), the shutter was closed and the current was reduced to cool the nickel. Once cooled, the chamber was vented and the apparatus containing the separator layer and the anode layer was removed from the thermal evaporator. [0269] The anode assembly was completed in an argon-filled glove box using electrically conductive adhesive transfer tape having a high adhesion side, a low adhesion side, and isotropic XYZ-axis electrical connectivity (sourced from 3M TM ) to attach a copper foil anode current collector to the deposited layer. The electrically conductive tape was double-sided and pressed onto the copper foil first. Then, the electrically conductive tape was pressed onto the deposited layer to form the anode assembly. The edges of the anode layer were sealed with a polymer via a melt process, forming a sealed anode assembly. A nickel tab was welded to the metal foil of the anode current collector to complete the sealed anode assembly. [0270] Scanning electron microscope (SEM) images of the nickel layer 1342 and the silver layer 1344 are shown in FIGS.13A-13F and 14A-14C. FIGS.15A and 15B show a cyclic voltage profile for the anode assembly (working electrode/separator) and a lithium metal reference electrode. The cycling was set at 20 µA/cm 2 relative to the area of the silver and nickel layers. As shown in FIG.15C, impedance was measured after 8 hours of cathodic current density at 20 µA/cm 2 in the frequency range of 2 MHz – 1 Hz. The open-circuit potential of the cell after assembly was 2.02 V. 45 49810322.1 [0271] Example 2: Battery Cell [0272] A cathode assembly was prepared with a cathode layer comprising a lithium nickel manganese cobalt oxide (NMC) and a cathode current collector comprising an aluminum metal foil. An aluminum tab was welded to the aluminum metal foil of the cathode current collector. [0273] The cathode layer was pressed against the separator layer of the anode assembly and integrated into an aluminum foil/polypropylene pouch. The cathode layer was wetted with a liquid catholyte. The pouch was sealed under vacuum conditions via an impulse/heat sealing process to complete the battery cell. [0274] FIGS.16A and 16B show a cyclic voltage profile for the battery cell. The cycling was set at 180 µA/cm 2 relative to the area of the cathode layer. As shown in FIG.16C, impedance was measured after 12 hours of first-cycle charge at 180 µA/cm 2 in the frequency range of 10 kHz – 0.1 Hz. The open-circuit potential of the cell after assembly was 0.38 V. [0275] Example 3: Copper/Indium Anode Assembly [0276] The anode assembly of Example 3 was prepared according to a procedure substantially similar to the procedure set forth in Example 1 except that a ~3.2 µm layer of copper was first deposited on the anode layer followed by a ~800 nm layer of indium. SEM images of the copper layer 1344 and the indium layer 1346 are shown in FIGS.17A-17C and 18A-18C. [0277] Example 4: Copper Anode Assembly [0278] The anode assembly of Example 4 was prepared according to a procedure substantially similar to the procedure set forth in Example 1 except Cuprum 81 (CuNex series sinter paste from Schlenk) was painted on the anode layer followed by attachment of a copper current collector and anode sealing. [0279] The Cuprum 81 was mixed in a planetary mixer for 5 mins at 500 rpm and applied in excess to the porous surface of the anode layer using a thin bristle paintbrush (size = 000). While the Cuprum 81 was wet, the excess was carefully removed with a squeegee to provide a substantially even layer having a thickness between 5-8 µm. [0280] The treated porous anode layer was dried under hot air (~100^C) applied evenly across the entire surface for ~5 min to evaporate solvents before sintering. The dried copper-treated anode layer and separator layer were placed in a box furnace (treatment side up) in an inert environment (argon, nitrogen) with no external pressure applied and sintered at a temperature of 500-700 ^C for ~ 2 hrs using a heat ramp of 30 ^C/min. The furnace was cooled (30 ^C/min) to 46 49810322.1 room temperature, and the sintered copper-treated anode layer and separator layer were removed from the furnace and placed onto a copper current collector wherein the copper-treated surface of the anode layer was physically attached to the copper current collector by contact with the current collector. The copper anode assembly was completed by anode sealing according to Example 1 and integrated into a test cell according to Example 2. FIG.19 shows voltage as a function of time during cell cycling (i.e., charging and discharging), wherein the test cell was charged and discharged at a current of (a) C/10 for cycles 1-3, (b) a current of C/5 for cycles 4 and 5, and (c) a current of C/2 for cycles 6-9. [0281] Example 5: Graphene Anode Assembly [0282] The anode assembly of Example 5 was prepared according to a procedure substantially similar to the procedure set forth in Example 1 except graphene in DMF (0.2 mg/mL) was deposited on the anode layer followed by attachment of a copper current collector and anode sealing. [0283] A solution of graphene in DMF (0.2 mg/mL) (Sigma Aldrich) was placed under 3Å molecular sieves for at least 2 weeks. The filtrate was decanted and vortexed for ~5 min with a CFNDISOP UOQSFW MJWFQ PQJOQ SO TRF' ,) _L OG SIF QFRTLSJNH ROLTSJON VBR EQOP DBRS ONSO SIF DFNSFQ of the porous side of the anode layer using a micropipette. The treated anode layer was dried at 140 °C for ~10 min to remove the DMF, and the work piece was then heated at 200 °C for ~ 30 min to anneal the deposited graphene. The anode assembly was sintered, attached to a copper current collector, and sealed according to Example 4. The sealed anode assembly was integrated into a test cell according to Example 2 which underwent charge cycling. FIG.20 shows voltage as a function of time during cell cycling (i.e., charging and discharging), wherein the test cell was charged and discharged at a current of (a) C/10 for cycles 1-3, (b) a current of C/5 for cycles 4 and 5, and (c) a current of C/2 for cycles 6-9.
