💡 Novelty & Significance:
The novelty lies in coupling oxygen-deficient In₂O₃₋ₓ catalytic sites with metallic In via a Schottky barrier, lowering electron-injection barrier potential. This dual engineering enables timely electron supply for polysulfide catalysis, accelerating sulfur redox kinetics and suppressing shuttling. Significance: 998 mAh g⁻¹ at 1 C, 0.038% decay per cycle, and 507.5 Wh kg⁻¹ pouch-cell energy density.
