💡 Novelty & Significance:
The novelty lies in a double-shelled TiO2 anode of cross-distributed 2 nm nanosheets armored with graphene-like carbon, enabling surface-controlled sodium storage. It achieves 2.13 mAh cm–2, 121 mAh g–1 at 100 C, and >90% retention over 3,000 cycles at 10.5 mg cm–2 loading, overcoming the capacity–rate–lifespan trade-off for practical high-power sodium batteries.
