| Abstract: Modified lithium manganese oxides were prepared by using LiMn2O4 and LiCoO2 as precursors by solid state reaction. A study has been carried out by TG-DSC, XRD and FTIR to analyze the reaction process and structural characterization of products. The results showed that the LiMn2O4 reacted chemically with LiCoO2 at high temperature. Li and Co atom could insert into the LiMn2O4 crystal lattice and obtained the Cobalt-Doped spinel compound. The results of constant-current cyclic test showed that the cyclic stability of the products are increased with the amount of doped LiCoO2, while their initial capacity is decreased. |
