Developing solid-state lithium metal batteries with wide operating temperature range is important in future. Polyethylene oxide (PEO)-based solid-state electrolytes are extensively studied for merits including superior flexibility and low glass transition temperature. However, ideal usage temperatures for conventional PEO-based solid-state electrolytes are between 60 and 65 °C, and unequable temperature degrades their electrochemical performances at low and high temperatures (≤25 °C and ≥80 °C).

- - The study involves creating yttrium trifluoride-doped polyacrylonitrile-based carbon nanofibers (YF-PAN-CNFs) through a specialized spinning process and carbonization, which enhances the performance of lithium metal battery separators.
- - These carbon nanofibers demonstrate high conductivity and a unique structure, significantly improving lithium ion and electron transport, and ensuring a uniform lithium plating/stripping process, leading to impressive cycling performance.
- - The YF-PAN-CNFs separator not only prevents lithium dendrite growth but also reduces the "shuttle effect" in lithium-sulfur batteries, suggesting its potential for broad applications in various high-performance rechargeable battery technologies.
