Abstract
The thermal stability of stoichiometric spinel phases in the system Li 1+deltaMn2-deltaO4 (0 less than or equal to delta less than or equal t o 0.33) has been investigated by high-temperature powder X-ray diffrac tion, differential thermal analysis, and thermogravimetric analysis. A t elevated temperatures, the lithium-manganese-oxide spinels undergo p hase changes by loss of oxygen and lithia (Li2O). The data highlight t he importance of temperature control when synthesising lithium-mangane se-oxide spinel compounds.
