Ionic Conductivity in Lithium and Lithium‐Sodium Beta Alumina

WebThe sodium is separated by a beta-alumina solid electrolyte (BASE) cylinder from the container of molten sulfur, which is fabricated from an inert metal serving as the cathode. The sulfur is absorbed in a carbon sponge. BASE is a good conductor of sodium ions above 250 °C, but a poor conductor of electrons, and thus avoids self-discharge. Web20 nov. 2024 · Li +-stabilized Na-β”-alumina was synthesized through sol-gel based on the Pechini method with Al(NO 3) 3, NaNO 3, and LiNO 3 as the metal precursor. Evaluations were done to several different sodium content in order to counterbalance Na2O losses during sintering, as well as different sintering temperature between 1500 – 1700 °C. high end body products
