摘要：

Amorphous solid electrolytes were formed by the interaction of cryptands or crown ethers with a lithium salt, Li[CF3SO2N(CH2)(3)OCH3], when the cavity size of the macrocycle does not match the diameter of the lithium cation. With the exception of [Li subset of 18-C-6] [(CF3SO2)(2)N] (the mathematical symbol of inclusion, subset of, is used to indicate Li+ included in 18-C-6), the complexes of Li[(CF3SO2)(2)N] with cryptand and crown ethers do not form amorphous electrolytes. Complexes of Li[CF3SO2N(CH2)(3)OCH3] and Li[(CF3SO3)(2)N] were examined by thermal, spectroscopic, and conductivity methods to determine the role of the anion on ionic glass formation.
