由Li 2S、P2 S5和LiCl通过湿磨和在500°C下后退火4小时合成了锂氧化银Li 6PS 5Cl粉末。在湿磨过程中使用有机溶剂如己烷、庚烷、甲苯和二甲苯。研究了湿磨Li 6PS 5Cl粉体和电解质的相演变、粉体形貌和电化学性能。与干磨相比，湿磨可显著缩短加工时间。溶剂的性质不影响离子电导率显着;然而，电子电导率的变化显着。研究表明，二甲苯和甲苯可以用于湿磨合成具有低电子和相当的离子电导率的Li 6PS 5Cl电解质粉末。使用二甲苯处理的Li 6PS 5Cl电解质的全固态电池在第一次放电循环中表现出192.4 mAh·g−1的最高放电容量和81.3%的库仑效率。
Lithium argyrodite Li6PS5Cl powders are synthesized from Li2S, P2S5, and LiCl via wet milling and post-annealing at 500°C for 4 h. Organic solvents such as hexane, heptane, toluene, and xylene are used during the wet milling process. The phase evolution, powder morphology, and electrochemical properties of the wet-milled Li6PS5Cl powders and electrolytes are studied. Compared to dry milling, the processing time is significantly reduced via wet milling. The nature of the solvent does not affect the ionic conductivity significantly; however, the electronic conductivity changes noticeably. The study indicates that xylene and toluene can be used for the wet milling to synthesize Li6PS5Cl electrolyte powder with low electronic and comparable ionic conductivities. The all-solid-state cell with the xylene-processed Li6PS5Cl electrolyte exhibits the highest discharge capacity of 192.4 mAh·g−1 and a Coulombic efficiency of 81.3% for the first discharge cycle.
