Key Points

This research aims to improve the performance of PEO-based electrolytes for all-solid-state batteries by addressing the limitations of PEO crystallinity.
Studied the effect of acetonitrile on the structural properties of Li3InCl6 and its influence on PEO-LiTFSI electrolytes.
Utilized structural analysis techniques to evaluate amorphization and performance characteristics at room temperature.
Found that the introduction of acetonitrile led to a significant enhancement in the amorphous nature of the PEO-LiTFSI electrolyte.
Observed increased ionic conductivity in modified electrolytes, facilitating room-temperature operation.

Abstract

Poly(ethylene oxide) (PEO)-based electrolytes are promising for all-solid-state batteries but are typically limited to elevated temperatures due to PEO crystallinity and strong Li⁺–EO coordination. Here, we report a homogeneous PEO–LiTFSI...
