摘　　要：利用非晶无机氧化物型与非晶无机硫化物型固体电解质二者在性能上能实现互补的现象,综合分析了LiPON/Li2S—SiS2—Li3PO4/LiPON复合多层膜非晶无机固体电解质结构性能.讨论了模型仍存在的物理问题.结果表明,该多层膜结构较大程度克服了各单层膜的缺点,表现出较高的离子电导率、较好的电化学稳定性及电极相容性.Amorphous inorganic oxide-based and sultid-based solid electrolytes are on supplementation of each other in performance. Performance on composite multilayer structure of amorphous inorganic solid electrolyte called LiPON/Li2S--SiS2--Li3PO4/LiPON is analyzed and physical problems in these electrolytes are briefly discussed as well. The analysis shows that this multi-layer structure so- called LiPON/LiES--SiS2--Li3PO4/LiPON overcomes the disadvantages of the each monolayer and shows higher ion conductivity, better electrochemical stability, and more superior compatibility with electrodes.
