  • DOPED SODIUM ANODE, BATTERY HAVING A DOPED SODIUM ANODE, AND METHODS OF USE THEREOF
    Publication number: 20230335724
    Abstract: An anode of a battery comprises sodium metal, and a dopant, in the sodium metal. The anode has a thickness of at most 80 µm, and the dopant is a metal with an electronegativity greater than sodium. A battery includes an anode, an anode charge collecting element in contact with the anode, a cathode, a cathode charge collecting element in contact with the cathode, an electrolyte in contact with the anode and the cathode, and a housing, enclosing the anode, anode charge colleting element, cathode, cathode charge collecting element and electrolyte. The anode in the battery comprises sodium metal doped with a dopant, and the dopant is present in an amount of 0.01 to 1.0 atomic percent.
