Abstract

Zn1-xCoxCO3 (ZCCO) microspheres were synthesized by a modified solvothermal method (ball milling-solvothermal combination method) using ZnCl2, CoCl2, and NH4HCO3 as raw materials. All samples were characterized by X-ray diffractometer (XRD), Fourier transform infrared spectra (FT-IR), and Scanning electron microscopy (SEM) technique. The results showed the introduction of Co and molar ratio of Zn and Co play crucial roles in the morphology and electrochemical performance of the ZCCO. As anode materials for lithium ion battery (LIB), all ZCCO electrodes possess high specific capacities and good cycle performance. The as-obtained Zn0.5Co0.5CO3 electrode exhibits higher discharge capacity (1526 mAh/g) and better rate properties with the reversible capacity of 976 mAh/g after 100 cycles when the molar ratio of Zn/Co is 1:1. Moreover, the present work provides a new and simple approach to the fabrication of novel anode materials (transition metal carbonates) for LIB applications.

21. Synthesis and electrochemical properties of spinel LiMn1.95M(x)O(4-y)F(y) for lithium ion batteries.

Abstract

Spinel phase LiMn1.95M(x)O(4-y)F(y) (M = Co and Y) were prepared by a rheological phase reaction method. The samples were characterized by X-ray diffraction, scanning electron microscopy, AC impedance, and galvanostatic charge/discharge profile measurement. These results showed that the LiMn1.95M(x)O(4-y)F(y) had better cycling performance than pure LiMn2O4. Among all the doped samples, the LiMn1.95Co0.03Y0.02O3.96F0.04 sample showed the best cycling performance, the initial discharge capacitiy is 129 mAh/g, and the discharge capacity of 124 mAh/g at a rate of 0.5 C after 50 cycles. The loss of its capacity was only 3.4%. The possible reasons for the outstanding electrochemical properties of LiMn1.95Co0.03Y0.02O3.96F0.04 are also discussed.
