Abstract

In this paper we show that the lithium manganese spinel, Li 1+ x Mn 2O 4 with lithium excess up to x=0.2 can be prepared using the Pechini-method which starts off with aqueous solutions of nitrates. The characterization of the samples by AAS and X-ray diffraction exhibits single phase material. X-ray absorption (XAS) experiments at the Mn–K edge lead to the conclusion that spinel with stoichiometry Li 1+ x Mn 2O 4 (0≤ x≤0.2) is formed.
