💡 Novelty & Significance:
Ferroelectric BaTiO₃-coated track-etched membranes with vertically aligned, low-tortuosity channels are introduced as separators for solid-state lithium metal batteries. Combined with in situ polymerized PDOL, they shorten Li⁺ pathways and homogenize electric fields, enabling dendrite-free plating, high conductivity (0.12 mS cm⁻¹), and stable cycling. This geometrically engineered ferroelectric separator paradigm advances safe, high-performance lithium metal batteries.
