<P><B>Abstract</B></P> <P>NiS hollow spheres were synthesized directly on the surface of Ni foam (NiS@NF) at room temperature via a simple electrodeposition in a KOH/thiourea solution without any Ni precursors. Morphological analysis revealed the formation of NiS hollow spheres, which consisted of nanoparticles. The NiS@NF nanocomposite exhibited a very high specific capacitance of 1553Fg<SUP>−1</SUP> (2.64Fcm<SUP>−2</SUP>) at a current density of 2.35Ag<SUP>−1</SUP> (4mAcm<SUP>−2</SUP>) in 6M KOH electrolyte. The NiS@NF nanocomposite also demonstrated excellent cycling stability (95.7% specific capacitance retention after 2000 cycles).</P> <P><B>Highlights</B></P> <P> <UL> <LI> NiS hollow spheres were electrodeposited directly on Ni foam at room temperature. </LI> <LI> The NiS@NF composite showed high specific capacitance: 1553Fg<SUP>−1</SUP> at 2.35Ag<SUP>−1</SUP>. </LI> <LI> The NiS@NF composite exhibited good cycling stability: 95.7% after 2000 cycles. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
