Dual-Stabilization Strategy Enabled High-Entropy Sulfide@Carbon Spheres for High-Performance Sodium Storage

Key Points

This research aims to enhance sodium-ion batteries by developing robust anodes that can withstand volume changes during sodiation.
Developed high-entropy sulfide@carbon spheres for use as anodes.
Evaluated performance metrics under simulated operating conditions.
Compared efficiency against traditional anode materials.
Achieved a significant increase in capacity retention after cycles, showing over 90% retention at 200 cycles.
Demonstrated a sodiation rate improvement of 30% compared to standard anodes.

Abstract

Despite their promise for grid-scale energy storage, sodium-ion batteries (SIBs) are hindered by the lack of robust anodes capable of tolerating severe volume changes during alloying-based sodiation. Herein, we present...
