微纳复合结构MFe2 O4负极材料的可控合成与性能
Controllable Synthesis and Performance of Micro-nano Structure MFe2 O4(M=Zn, Co) in Lithium-ion Batteries
摘要
Abstract
Micro-nano structure MFe2O4(M=Zn, Co) materials were synthesized directly by hydrothermal method. The structural and morphological properties of the samples were investigated by means of X-ray diffraction( XRD) and transmission electron microscopy( TEM) . The electrochemical performance of MFe2 O4 ( M=Zn, Co) was examined by galvanostatic charge-discharge test and electrochemical alternate current( AC) impedance technique. The results show that hollow sphere CoFe2 O4 and ZnFe2 O4 have a reversible capacity of 1180 and 655 mA·h/g after 50 cycles, which are higher than those of solid sphere materials. At the same time, the formation mechanism of different morphology was studied.关键词
