Abstract
Advances in solid state battery research continue to improve the future potential for widespread adoption, however electrolyte performance under mechanical compression is largely unknown. In this thesis experimental testing work is carried out to show that ionic conductivity decreases in 18:1 PEO-LiTFSI under mechanical compression. Furthermore the composite PEO-LiTFSI with 10 wt% LLZTO was tested, showing that the change in ionic conductivity is reduced compared to PEO-LiTFSI without filler. Finite element method simulations are carried out for PEO-LiTFSI with and without LLZTO, corroborating that the change in ionic conductivity in the presence of filler particles is expected to be lower compared to PEO-LiTFSI without LLZTO, though change in slope is smaller than found experimentally.
