Low-temperature densification of Al-doped Li7La3Zr2O12: a reliable and controllable synthesis of fast-ion conducting garnets
The application of Li7La3Zr2O12 as a Li + solid electrolyte is hampered by the lack of a reliable procedure to obtain and densify the fast-ion conducting cubic garnet polymorph. Dense cubic Li7La3Zr2O12-type phases are typically formed as a result of Al-incorporation in an unreliable reaction with the alumina crucible at elevated temperatures of up to 1230 C. High Al-incorporation levels are al...

متن کاملEffects of Al Doping on the Properties of Li7La3Zr2O12 Garnet Solid Electrolyte Synthesized by Combustion Sol-gel Method
Li7La3Zr2O12 (LLZO) garnets are one of the promising materials as electrolytes for solid-state batteries. In this study, Li7-3xAlxLa3Zr2O12 (x= 0.22, 0.25, and 0.28) garnet is synthesized using the combustion sol-gel method to stabilize the cubic phase for higher ionic conductivity. The X-ray diffraction (XRD) results of as-synthesized powders reveal that by addition of 0.22 and 0.25 mole Al, t...
متن کاملLOW TEMPERATURE SYNTHESIS OF NANOCRYSTALLINE MgAl2O4 SPINEL VIA SUCROSE PROCESS
Abstract: Nanocrystalline MgAl2O4 spinel powder was synthesized using metal nitrates and a polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). According to XRD res...
