Surface treatment of a solid electrolyte to lower the interfacial resistance between the solid electrolyte and an electrode |
| abstract |
Disclosed are electrochemical devices, such as sodium ion conducting solid state electrolytes, sodium battery electrodes, and solid-state sodium metal batteries including these electrodes and solid state electrolytes. One example method for preparing a sodium/sodium-β"-alumina interface with low interfacial resistance and capable of achieving high current density in an electrochemical cell includes the steps of: (a) providing a precursor electrolyte having a resistive surface region, wherein the precursor electrolyte comprises sodium-β"-alumina; (b) removing at least a portion of the resistive surface region; (c) heating the precursor electrolyte thereby forming a solid state electrolyte, and (d) placing a side of the solid state electrolyte in contact with a sodium anode. |
