  • Metallic Foam Anode Coated with an Active Oxide Material
    Publication number: 20230278097
    Abstract: A three-dimensional metallic foam is fabricated with an active oxide material for use as an anode for lithium batteries. The porous metal foam, which can be fabricated by a freeze-casting process, is used as the anode current collector of the lithium battery. The porous metal foam can be heat-treated to form an active oxide material to form on the surface of the metal foam. The oxide material acts as the three-dimensional active material that reacts with lithium ions during charging and discharging.
