💡 Novelty & Significance:
The novelty lies in a discontinuous, spray-coated Bi0.4Sb1.6Te3 sodiophilic interface on ultralight Al foil, contrasting dense coatings. This enables uniform Na nucleation, fast lean-electrolyte wetting, and stable anode-free sodium batteries. Significance: 5C charging over 400 cycles and a 2.75-Ah pouch cell achieving 205 Wh kg−1 with lean electrolyte, advancing practical high-energy sodium metal batteries.
