Solid state electrolyte has gained much attention because of durability, reliability, no flammable component. As a good candidate, high dense Li-β-Al2O3 electrolyte materials have been synthesized via multiple methods. Direct synthesis was reported to prepare pure Li-beta-alumina ion conductor. Many attempts were investigated to lower sintering temperature. And the effect of the microstructure and oxygen deficiency to ionic conductivity was also studied. The properties and microstructures of the prepared samples were studied by X-ray diffraction (XRD), scan electron microscope (SEM) and ionic conductivity tests.
