Abstract

Three-dimensional (3D) porous NiCo2S4 nanonetworks were fabricated on nickel foam (NF) through an anion exchange reaction between NiCo2O4 nanosheets (hydrothermally grown on NF) and Na2S, and showed a very high specific capacitance of 1501.2 F g−1 at 1 A g−1 (even 2.5 times higher than that of NiCo2O4 nanosheets) and robust cycling stability for supercapacitors.
