Partially delocalized charge in Fe-doped NiCo2S4 nanosheet–mesoporous carbon-composites for high-voltage supercapacitors

Unraveling the effect of transition-metal doping on the energy storage properties of bimetallic sulfides remains a grand challenge. Herein, we construct bimetallic sulfide nanosheets and hence deliberately introduce transition-metal doping domains on their surface. The resulting materials show not o...
