Abstract

Garnet-type oxides, Li₅La₃M₂O₁₂ (M = Nb, Ta) are a group of materials that exhibit high electrochemical stability and high conductivity for Li ions, making them promising electrolyte materials for all-solid-state Li-ion batteries. Li ion conductivity can continue to be increased by substituting alkaline earth and Li ions for La³⁺ in the structure. Our recent work has shown a simple empirical relation between concentration of Li and ionic conductivity in several garnet-type compounds. The occupation of Li ions in various crystallographic sites also appears to control Li ion conductivity in the garnet-type structures. In the present paper, we report current progress in garnet-based Li ion electrolytes and also discuss the effect of chemical doping on ionic conductivity and chemical stability of Li₅La₃Nb₂O₁₂ in water and organic acids.
