Low temperature route to nanocrystalline LiMn2O4 spinel
2006
Abstract Nanocrystalline LiMn 2 O 4 spinel was successfully prepared at the temperature as low as 200 °C via solution combustion method, employing lithium acetate and manganese acetate as Li–Mn source, citric acid as chelating and combusting agent. The XRD patterns show it is a reaction-controlled process. And the morphology was investigated by transmission electron microscope (TEM) images and scanning electron microscope (SEM) images. A possible mechanism for the formation of LiMn 2 O 4 has also been discussed.
