🔬 Research Article

💡 Novelty & Significance:
The study introduces a Janus Ag nanoskin-armored polyimide bilayer separator that regulates lithium nucleation via a lithiophilic 3D host, suppressing dendrite growth. It achieves high Coulombic efficiency (98.9%), Li⁺ transference number (0.70), and 1600 h cycling stability. This universal strategy enables dendrite-free lithium metal batteries with improved safety and performance.
