Fabrication of a porous NiS/Ni nanostructured electrode via a dry thermal sulfuration method and its application in a lithium ion battery

A novel dry thermal sulfuration approach has been used to fabricate a porous NiS/Ni nanostructured cathode electrode. Galvanostatic battery testing shows that the NiS/Ni electrode exhibits high discharge/charge capacity and excellent cycle performance. The performances are due to its favorable porous structure and the fine electrical contact between NiS and Ni.
