In the synthesis process of cathode materials, the synthesis method as well as synthesis route is important because cathode materials are very sensitive to the preparation process. Thermal behaviour of the precursors obtained during the synthesis process will indicate if pure and single products can be obtained after annealing. The synthesis method used here is the self-propagating combustion (spc). LiMn1/3Co1/3Ni1/3O2 and LiMn0.3Co0.3Ni0.3Ti0.1O2 are two types of cathode materials synthesized using this method. The TG/DSC of the materials indicates that the LiMn0.3Co0.3Ni0.3Ti0.1O2 is formed at a lower temperature than LiMn1/3Co1/3Ni1/3O2 material. Therefore, annealing the materials at different temperatures and durations will result in differences of the materials’ characteristics that will affect their electrochemical behaviour. These materials’ characteristics will affect the electrochemical performance of the cathodes. The reasons for the differences in electrochemical performances can be attributable to the phases, purity, crystallite size and the crystallinity of the materials.
