Polymer solid electrolytes-PEO and alkali halides: A modified preparative technique
Abstract Polymer solid electrolytes are prepared by a modified preparative technique without any additional solvent. By this technique the polymer solid electrolyte can be manufactured not in thin films but in a compact form, particularly disks or tablets. The conductivities of these PEO-based electrolytes are investigated depending on temperature, molecular weight of PEO and alkali halide content. For the system PEO/LiI the composition dependence of the lithium ion transport numbers are investigated. In the range of low salt content the results are similar to those obtained from thin film preparations.
