Summary: Constructing an efficient artificial solid electrolyte interface (SEI) film is crucial for the practical application of lithium metal batteries. In this study, a dense artificial SEI film consisting of lithiophilic Zn/LixZny dispersed in consecutive Li+-conductors of LixSiOy, Li2O, and LiOH is successfully constructed. The consecutive Li+-conductors promote the desolvation process of solvated-Li+ and regulate the transfer of lithium ions, while the nonconsecutive lithiophilic metals are polarized to enhance the transfer of lithium ions and reduce nucleation barrier. The achieved results include low polarization of approximately 50 mV for 750 h at 2.0 mA cm(-2) in symmetric cells and high capacity retention of 99.2% in full cells with a high lithium iron phosphate loading.

Summary: By employing a coaxial wet-spinning assembly strategy, multifunctional hollow core-shell fibers with a ductile polyvinylidene fluoride (PVDF) shell and compactly ordered MXene hollow core were fabricated to achieve satisfactory chemical resistances, high electrical conductivity, and enhanced ductility. The partial hydroxylation of PVDF during coagulation enhanced the interfacial interaction between the PVDF and MXene layers. The hollow core, consisting of a compact and ordered MXene layer, provided the fibers with high electrical conductivity, while the PVDF shell endowed them with enhanced ductility and excellent resistances to acid, alkali, and seawater. The hollow core-shell structure made the fibers lightweight and facilitated multiple scattering of electromagnetic waves, resulting in increased electromagnetic wave absorption and attenuation. The resulting fibers exhibited exceptional Joule heating performances and a high electromagnetic interference shielding effectiveness, making them promising for wearable heating and electromagnetic interference shielding applications.
