Fabrication of NaNiF3/Ni composite and its application in lithium ion batteries

NaNiF3/Ni composite material is successfully synthesized by a novel electrochemical corrosion method. The morphology and size of the as-prepared composite material are studied by field emission scanning electron microscopy (FE-SEM). The results indicate that the NaNiF3 shows particle-like morphology with mean size about 3 mu m, which grows directly on the surface of Ni foam. Electrochemical properties of the NaNiF3/Ni as anode for lithium ion batteries are studied by conventional charge/discharge test, which show obvious voltage plateaus in charge/discharge curves, endowing it with potential application in lithium ion battery.
