Abstract

Amorphous (a-) Sb₂S₃ nanoparticle aggregates were synthesized using a facile polyol-mediated process at room temperature and their Na-ion storage capability was evaluated. Owing to the spherical nano-aggregate morphology and amorphous structure, the a-Sb₂S₃ anode exhibited superior rate capability and cycling stability compared to that of crystalline, microscale Sb₂S₃ particles. The a-Sb₂S₃ electrode was also examined as an anode for eco-friendly, Na metal-free seawater flow batteries.
