Abstract :
[en] To meet the increasing energy demand for electric vehicles, renewable and grid storage systems, the design and the manufactory of new electrode materials is crucial. Recently, huge efforts have been oriented to the development of high capacity anode material as one of the important components for next-generation lithium-ion batteries. Compared to graphite which dominates the LIBs anode market, nanostructured metal oxides have demonstrated promising properties such as higher specific capacities and lower working potential, and hence can be regarded as tempting candidates for the long term application [1].
In this work, cobalt ferrite oxide CoFe2O4 has been prepared by the alginate gelling method. The face-centered cubic spinel structure and the spherical morphology of the produced material were confirmed using XRD, Raman spectroscopy, and SEM techniques. As anode material for LIBs, the material exhibits good cycling and multi-rate capability performances (976 mAh g-1 at C/5 and 570 mAh g-1 at 2C). To go further and to understand the lithiation/delithiation mechanism in-situ XRD and Ex-situ Mössbauer spectroscopy techniques have been performed.
