  • Method to Improve Sodium Electrochemical Interfaces of Sodium Ion-Conducting Ceramics
    Publication number: 20230207787
    Abstract: The present invention is directed to the modification of sodium electrochemical interfaces to improve performance of sodium ion-conducting ceramics in a variety of electrochemical applications. Enhanced mating of the separator-sodium interface by means of engineered coatings or other surface modifications results in lower interfacial resistance and higher performance at increased current densities, enabling the effective operation of molten sodium batteries and other electrochemical technologies at low and high temperatures.
    Type: Application
