Li(1+x)Mn2O4 powder has been prepared with starting material of Li2CO3 as lithium source and MnO2 as manganese source. The preparation was done by powder metallurgy with varying Li addition in weight% of 5%, 10%, 15% and 30%. From Differential Thermal Analisys (DTA) data , it is revealed that calcination andsintering temperature are at 700 °C and 800 °C respectively. The characterisation results showed that all XRD patterns are similar for all composition of Li addition, but different in intensity. The diffraction data was analyzed by Rietveld method to get lattice parameter unit cell volume and crystal density. The lattice parameters reach optimum at 15% of Li addition. The cell volume increased could lead to better intercalation properties ofthis powder. Li ion can intercalate easier in this unit cell which make Li(1+x)Mn2O4 can be used as a cathodematerial.Keywords: Li(1+x)Mn2O4, Powder metallurgy method, Rietveld Analysis, Intercalation property.
