Carbon Dots/NiCo2O4Nanocomposites with Various Morphologies for High Performance Supercapacitors

A series of carbon dots/NiCo2O4 composites with various morphologies are prepared and tested for supercapacitors. These samples have good electrical conductivities and efficient ions transport paths, so they exhibit high specific capacitances, superior rate performances, and high cycling stabilities. The optimal composite for hybrid supercapacitor exhibits a high energy density up to 62.0 Wh kg−1.
