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.

Abstract The development and application of solid‐state electrolytes (SSEs) play a crucial role in advancing lithium metal batteries (LMBs). Consequently, the search for high‐performance, economic, easily fabricated SSEs has become prevailing trend. In this work, we explore an alternative approach to design traditional commercial lithium‐ion cathode material, spinel‐type LiMn 2 O 4 (LMO) as SSE. By blending LMO with poly(vinylidene difluoride) combining two layers polyethylene (PE) film on top bottom, effectively reduce its high electronic conductivity, thereby creating PE/LMO/PE SSE demonstrates ionic conductivity (3.15 × 10 −4 S cm −1 at 35°C), low (7.31 −11 ), good interfacial contact stability both anode, LiFePO nickel‐rich Li[Ni 0.8 Co 0.1 Mn ]O cathodes.
