In order to make best use of the superior electrochemical properties of nickel sulfide (NiS) as
an electrode material for supercapacitors, increase in surface area through electrode
nanostructuring is one of the major issues. However, currently used NiS nanostructuring
methods, such as hydrothermal and solvothermal techniques, require high-temperature,
long and complicated nano-processes, and hence are not suitable for practical use. In this
work, we developed a new, simple method for fabricating porous, nanostructured NiS …
