以丙酸乙酯为溶剂，在短短30min内一锅合成了Li2S-P2S5-LiI固体电解质前驱体。将Li2S、P2S5和LiI粉末在溶剂中摇动不同时间。将前驱体悬浮液在室温(RT)下抽真空，加热至170℃保温2 h，得到Li7−0.08xP2S8−0.04xI固体电解质。当x=1，振荡时间为45min时，获得了高达4.6×10−4 S cm−1的离子电导率。电解液前驱体在30分钟内形成是迄今报道的最短时间。
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.
