Among the Li-ion conducting inorganic materials, lithium lanthanum zirconate (LLZO) is believed to possess good chemical stability against Li metal and hence considered to be a promising solid electrolyte for Li-ion batteries. However, systematic sets of studies conducted here at regular intervals during storage of Al-doped LLZO (cubic garnet) sint...

Electrolytes with high lithium-ion conductivity, better mechanical strength and large electrochemical window are essential for the realization of high-energy density lithium batteries. Polymer electrolytes are gaining interest due to their inherent flexibility and nonflammability over conventional liquid electrolytes. In this work, lithium garnet c...

AbstractIn this paper, we report low temperature, fast synthesis of Li6MLa2Nb2O12 (M = Ca, Sr, Ba) with the cubic garnet structure by sol–gel process. The optimized synthesis condition is 775 °C for 6 h with 10% excess lithium salt. The calcination temperature is nearly 125 °C lower than that in the solid state reaction, and the calcination time(~6...

A cubic Li5La3Nb2O12 phase with a garnet framework was synthesized by the sol–gel process, in which lithium hydroxide, niobium oxide and acetic lanthanum were used as starting materials, while water was used as solvent. Pure garnet-like Li5La3Nb2O12 powders were obtained after heating the gel precursor at 700 °C for 6 h with 10 % excess lithium sal...
