Synthesis of porous NiS thin films on Ni foam substrate via an electrodeposition route and its application in lithium-ion batteries

Electrodeposition, a convenient approach, has been used for fabricating porous NiS thin films on Ni foam substrate. The obtained NiS/Ni thin films were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and energy dispersive spectrometry. Furthermore, the electrodeposited NiS/Ni thin films were first used as the anode for lithium-ion intercalation and exhibited large capacities and good cycling stability. (C) 2013 Elsevier B. V.
