Zn substitution NiFe2O4 nanoparticles with enhanced conductivity as high-performances electrodes for lithium ion batteries

摘要: Abstract Zn2+ ion substituted nickel ferrite nanomaterials with the chemical formula Ni1−xZnxFe2O4 for x = 0, 0.3, 0.5, 0.7 and 1 have been synthesized by a facile green-chemical hydrothermal method as anode materials in lithium battery. The morphology structure of samples were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM) transmission (TEM). physical electrochemical properties tested system. Furthermore, energetic electronic investigated density functional calculations. results suggest that Zn substitution can affect conduction performance zinc - ferrite. Meanwhile, show an enhancement capacity increasing concentration is observed especially x = 0.3 which exhibit high discharge 1416 mAh g−1at end 100th cycle. Moreover, theoretical research yield synthesis strategy described present work holds promise general fabrication other metallic elements complex transition metal oxides power LIBs.
