Formation of Onion‐Like NiCo₂S₄ Particles via Sequential Ion‐Exchange for Hybrid Supercapacitors

Abstract

Onion-like NiCo2S4 particles with unique hollow structured shells are synthesized by a sequential ion-exchange strategy. With the structural and compositional advantages, these unique onion-like NiCo2S4 particles exhibit enhanced electrochemical performance as an electrode material for hybrid supercapacitors.
