Abstract
In the present work, argyrodite Li6PS5Cl sulfide solid electrolyte is prepared by a liquid phase process, consisting of two steps: (1) suspension-reaction under the ultrasonication of Li2S, P2S5, and LiCl precursors in acetonitrile and, (2) dissolution-precipitation involving the addition of ethanol/acetonitrile and solvents removal by heating at 180 °C. The effect of the addition of a nonionic surfactant on the properties of the sulfide solid electrolyte is also studied. The synthesis process allows to obtain Li6PS5Cl argyrodite solid electrolyte with high ionic conductivity of 2.0 × 10−4 S cm−1, the low activation energy of 0.22 eV, and electrochemical stability up to 5 V (vs. Li). A regular particle distribution with a size smaller than 1 μm is obtained by the addition of the surfactant.
本研究采用液相法制备银汞石Li6PS5Cl硫化物固体电解质，包括两个步骤:(1)Li2S、P2S5和LiCl前驱体在乙腈中超声作用下的悬浮反应;(2)加入乙醇/乙腈并在180℃下加热去除溶剂的溶解沉淀。研究了非离子表面活性剂的加入对硫化固体电解质性能的影响。该合成工艺可获得离子电导率高达2.0 × 10−4 S cm−1、活化能低至0.22 eV、电化学稳定性高达5 V (vs. Li)的银镁石固体电解质。加入表面活性剂后，得到了粒径小于1 μm的均匀颗粒分布。
期刊介绍：
The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
