Abstract: PEO-based composite polymer electrolytes are reinforced by Janus nanofibers that feature distinct Li⁺ transport channels and remarkable thermal stability. The resulting all-solid-state lithium-metal batteries demonstrate ultra-long cycle life, even under mechanical deformation (folding, piercing, cutting), and show excellent compatibility with LiFePO₄ and LiNi₀.₈Mn₀.₁Co₀.₁O₂ cathodes.

Abstract: The authors develop a double-layered solid composite electrolyte (DLSCE) by integrating a polymer layer (PVDF-based) with an inorganic filler layer. This design enhances ionic conductivity, mechanical strength, and interfacial stability, leading to improved cycling performance in lithium-metal solid-state batteries.
