A one-pot synthesis of Li2S–P2S5–LiI solid electrolyte precursors in a short time of 30 min is demonstrated by using ethyl propionate as a solvent. Li2S, P2S5 and LiI powders were shaken for different times in the solvent. The precursor suspension was evacuated at room temperature (RT) and then heated to 170 °C for 2 h to obtain Li7−0.08xP2S8−0.04xI solid electrolytes. A high ionic conductivity up to 4.6 × 10−4 S cm−1 at RT was achieved with x = 1 and a shaking time of 45 min. The formation of electrolyte precursors in 30 min is the shortest time that has ever been reported.

Li 2 S–P 2 S 5 –LiI固体电解质前体的快速合成

通过使用丙酸乙酯作为溶剂,证明了在短短30分钟内一锅法合成Li 2 S–P 2 S 5 –LiI固体电解质前体。Li 2 S,P 2 S 5和LiI粉末在溶剂中振摇不同的时间。将前体悬浮液在室温(RT)抽真空,然后加热到170°C保持2小时,以获得Li 7-0.08 x P 2 S 8-0.04 x I固体电解质。x可以实现高达4.6×10 -4 S cm -1的高离子电导率= 1,摇动时间为45分钟。30分钟内电解质前体的形成是有史以来最短的时间。
