Abstract

A 3D highly conductive urchin-like NiCo₂S₄ nanostructure has been successfully prepared using a facile precursor transformation method. Remarkably, the NiCo₂S₄ electroactive material demonstrates superior electrochemical performance with ultrahigh high-rate capacitance, very high specific capacitance, and excellent cycling stability.
