摘要

Solid electrolytes present promising options for developing future-generation battery technology, primarily because they eliminate concerns related to leaking, combustibility, and chemical resistance. Inorganic particles serve as substances within solid polymeric material electrolytes, combining with polymer compounds and lithium salts to enhance electrochemical efficiency and stability in structure. The addition of MXene (15 Wt%) ceramic powder makes composite polymer electrolyte membrane MXene (15 Wt%) exhibit excellent electrochemical performance, demonstrating an ionic conductivity of 1.08 × 10–4 S cm−1 at ambient temperature, a lithium exchange number of 0.63, an electrochemical window of 4.0 (V), thermal shrinkage up to 250 °C, the porosity of ~ 93%, electrolyte uptake of ~ 230%, and activation energy of 0.23 (eV). The prepared MXene (15 Wt%) demonstrates excellent electrochemical performance, providing an effective design strategy for solid-state lithium-based batteries.
