采用机械球磨法制备了由玻璃和离子液体组成的复合固体电解质。所得复合物的电导率与离子液体的电导率有关。1-乙基-3-甲基咪唑四氟硼酸盐的加入导致玻璃的电导率下降，因为在球磨处理过程中，1-乙基-3-甲基咪唑四氟硼酸盐分解并形成高电阻化合物。然而，具有10摩尔%的1-乙基-3-甲基咪唑鎓双（氟磺酰基）酰胺与双（三氟甲磺酰基）酰胺锂的复合物在室温下显示出高的电导率。所得复合材料显示出超过5V的宽电化学窗口，并显示出对锂金属的电化学稳定性。
Composite solid electrolytes composed of (mol%) glass and an ionic liquid were prepared by using a mechanical milling technique. The conductivities of the obtained composites were related to the conductivities of ionic liquids. The addition of 1-ethyl-3-methyl imidazolium tetrafluoroborate to the glass led to the decrease in conductivity because the was decomposed and high resistive compounds would be formed during the milling treatment. However, the composite with 10 mol% of 1-ethyl-3-methyl imidazolium bis (fluorosulfonyl) amide with lithium bis (trifluoromethanesulfonyl) amide showed a high conductivity of at room temperature. The obtained composite showed a wide electrochemical window of over 5 V and showed an electrochemical stability against lithium metal.
