采用脉冲激光沉积法将80Li(2)S中心点20P(2)S(5)(mol%)固体电解质涂覆在LiCoO2电极颗粒上，制备了用于全固态锂二次电池的电极/电解质复合材料。横截面透射电子显微镜图像显示，固体电解质层形成在LiCoO2颗粒上。使用涂覆有固体电解质的LiCoO2颗粒的全固态电池进行充放电，并表现出良好的循环性能。这表明电解质涂层为LiCoO2提供了锂离子传导路径，并且该技术在全固态电池的开发中是有效的。 (C) 2010 年电化学协会。 [DOI：10.1149/1.3376620] 保留所有权利。
Electrode/electrolyte composite materials for all-solid-state lithium secondary batteries were prepared by coating the 80Li(2)S center dot 20P(2)S(5) (mol%) solid electrolyte onto LiCoO2 electrode particles using the pulsed laser deposition method. Cross-sectional transmission electron microscopy images showed that the solid electrolyte layer was formed on the LiCoO2 particles. The all-solid-state cell using the LiCoO2 particles coated with the solid electrolyte was charged and discharged, and exhibited good cycle performance. This suggests that the electrolyte coatings provide a lithium-ion conduction path to LiCoO2, and the technique is effective in the development of all-solid-state cells.
