| 内容記述 | We investigated the properties of Al-free garnet related Li7La3Zr2O12 (LLZ) and Li7-xLa3Zr2-xTaxO12 (LLZTa) with Ta content x = 0.25, 0.5 and 1.0 synthesized by a solid state reaction method. It was confirmed that all Al-free LLZTa have the cubic garnet related structure, while Al-free LLZ without Ta substitution has tetragonal one. No other secondary phases were observed in all sintered samples. This indicates that partial substitution of Zr4+ by Ta5+ with higher valence increases Li-ion vacancy concentration in a garnet framework and stabilizes cubic garnet structure. The LLZTa grains are in good contact with each other although a certain amount of pores in the boundary area can be observed. Total (bulk + grain boundary) Li-ion conductivity at 27°C for all Al-free LLZTa were well above 10-4 Scm-1, while Al-free LLZ showed much lower room temperature conductivity of 1 × 10-5 Scm-1. The highest room temperature conductivity of 6.1 × 10-4 Scm-1 was obtained in Al-free LLZTa with x = 0.5, which is approximately 30−40% lower than the value in LLZTa (x = 0.5) with Al inclusion as previously reported. | |||||
