Quantum-Size FeS2 with Delocalized Electronic Regions Enable High-Performance Sodium-Ion Batteries Across Wide Temperatures

Highlights Quantum-scaled FeS2 induces delocalized electronic regions, effectively reducing electrostatic potential barriers and accelerating Na+ diffusion kinetics. The free charge accumulation regions were formed by edge mismatched atoms, activating numerous electrochemically sites to enable high-...
