Sn 4 P 3 @C as a High‐Capacity Additive to Reinforce Hard Carbon Anodes for Practical High‐Performance Sodium‐Ion Batteries

ABSTRACT Sodium‐ion batteries (SIBs) are promising for large‐scale energy storage, yet their energy density is constrained by anode materials. Commercially mature hard carbon (HC) suffers from low capacity, initial Coulombic efficiency (ICE), and tap density, whereas high‐capacit...
