摘要：

The mixed transition-metal spinel oxide CoFe2O4 Was prepared through a co-precipitation method. The resulting sample was characterized by XRD, SEM and XPS. The electrochemical performances of CoFe2O4 as active material for lithium ion battery were tested in the Teflon cells. It is found that the first discharge capacity is close to 882 m h g(-1) at a current density of 0.2 A cm(-2), corresponding to the reaction of 7.7 Li+ per CoFe2O4. And the mechanism of the reaction of lithium with cobalt ferrite spinel was discussed. (c) 2005 Elsevier B.V. All rights reserved.
