  • Method of improved treatment relating to the surface of the electrolyte for a solid electrolyte cell
    Patent number: 3963522
    Abstract: The method of improved treatment relating to the surface of the electrolyte for a solid electrolyte cell of Na.sup.+ ion conduction type is disclosed. Conductive paint containing unoxidized metal powder such as silver, gold or mixtures thereof is coated on the surface of said solid electrolyte and sintered in the range 700.degree.-900.degree.C so that faradaic impedance at the electrode-electrolyte interface is lowered. After sintering, the solid electrolyte is treated with fused sodium nitrate salt to prevent characteristic changes during extended storage.
