摘要: The Zn-doping Li4-2xZn3xTi5-xO12(0 &le 3x &le 0.2) as anode materials for lithium-ion batteries were synthesized by a solid-state method. The morphology and microstructure of the samples were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), mastersizer 2000 laser granularity analysis (MS2000), and tap density analysis. The relative capacity and the cycle characteristics of the Zn-doping Li4Ti5O12 have been tested, and then the samples were characterized by AC impedance spectroscopy and cyclic voltammetry. The Zn2+ did not change the crystal structure, but enhanced the tap density of the materials. The results showed that the Zn-doping reduced the polarized voltage and improved the electrochemical performance of the materials. When the ratio of the n(Li):n(Zn):n(Ti) was 3.933:0.1:4.967, the first charge capacity of the Zn-doping Li4Ti5O12 was 160mAh/g with a current density 1C, and after 60 cycles it was still 138mAh/g.
