摘要

Utilizing low-molecular weight polyethylene oxide (L-PEO) for SPE using free-solvent casting technique presented a challenge in terms of electrochemical properties and formability issues. In this study, TEMPO-oxidized NC is utilized as a reinforcing agent to increase free volume and segmental motion of a solid-state L-PEO composite, which allows Li⁺ ion transport and prevents mechanical instability. During the breaking-forming process of Li–O bonds, ion transport occurs at a 40 EO/Li molar ratio, which is stabilized by NC structural network via intrachain or interchain hooping. The ion transport of the SPE-C electrolyte membrane fullfill Arrhenius behavior with increasing ionic conductivity.
