Lithium–sulfur batteries (LSBs) exhibit high theoretical specific capacities, abundant resource reserves, and low costs, making them promising candidates for next-generation lithium-ion (LIBs). However, significant challenges, such as the shuttle effect volume expansion, hinder their practical applications. To address these issues, this study introduces a unique intermediate layer comprising N-doped carbon nanofiber/TiO2/diatomite (NCNF/TiO2/DE) from perspective of membrane modification. The comprises nitrogen-doped titanium dioxide/carbon nanofiber (NCNF/TiO2) materials, with diatomite filling fiber gaps. This forms three-dimensional (3D) conductive network that provides ample space sulfur expansion numerous adsorption active sites, thereby accelerating electrolyte penetration diffusion. These features collectively contribute to outstanding electrochemical performance battery.

Gel polymer electrolytes (GPEs) have become a viable substitute for liquid (LEs) in lithium metal batteries (LMBs) their excellent ionic conductivity and enhanced interfacial compatibility. However, as semisolid electrolytes, GPEs face significant challenges, including low mechanical strength flammability. Herein, we fabricate porous poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) mat (PHL) enriched with oxide ceramics support matrix, fluorine-rich compounds are incorporated by situ polymerization to construct flame-retardant cross-linked GPE network improved The PHL-based (PHL-GPE) exhibits ultralong cycling stability of over 2000 h metal. When applying Li|PHL-GPE|LiFePO4 (LFP) cells, the PHL-GPE enables stable 500 cycles capacity retention 92.3% under high current density (1C) active material mass loading (11.25 mg cm–2). This study provides an approach address key challenges commercialization LMBs.
