Abstract	Lithium garnets are considered as advanced solid electrolytes for safe and high-energy-density solid-state lithium batteries. A multi-substituted strategy illustrating in this work is substitution of Li by Ga and Zr by Ta/Ba, therefore stabilizing and densifying the cubic lithium garnets thus improving the ionic conductivities. The influence of Ga substitution on garnet phase, microstructure and conductivity of Li6.7-3xGaxLa3Zr1.55Ta0.4Ba0.05O12 garnets is systematically studied. The developed multi-substituted garnet-type electrolytes demonstrate high ambient-temperature conductivity of 1.02 x 10(-3) S cm(-1). Moreover, the multi-substituted garnet reveals impressive capability of alleviating lithium metal dendrites over 800 h under current of 0.01 mA cm(-2) to 0.5 mA cm(-2), promising solid-state battery applications.
