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. WebSodium-beta alumina is a solid-state electrolyte with outstanding chemical, electrochemical, and mechanical properties. Sodium polyaluminate is successfully employed in established Na–S and Na–NiCl2 cell systems. It is a promising candidate for all-solid-state sodium batteries. However, humidity affects the performance of this solid ...

β-alumina is a solid electrolyte. Solid-state electrolytes are solids with high ionic conductivity, comparable to those of molten salts. Solid-state electrolytes have applications in electrical energy storage and various sensors. They can be used in supercapacitors, fuel cells and solid-state batteries, substituting liquid electrolytes used in for example the lithium-ion battery. The solid electrolyte contains highly mobile ions, allowing the movement of ions. The ions move by hoppi… WebLi+-Na+ beta alumina, a sample disk pre-pared by thermal exchange was incorpo-rated into a Li/Li+-Na+ beta alumina/Br2 test cell. Propylene carbonate containing LiCIO4 and LiBr was the liquid electro-lyte, and the Li electrode was formed in situ by deposition of Li on a Ni foam substrate.
