Single phase LiMn0.3Co0.3Ni0.3Ti0.1O2 materials are prepared using a self-propagating combustion method. The structure and morphology of the materials were characterized using X-Ray powder diffraction (XRPD) and Field Emission Scanning Electron Microscopy (FESEM). The electrochemical performances of the materials were characterized by means of galvanostatic charge-discharge test on the fabricated cells. XRD results showed that the materials are impurity-free and single phase with well ordered hexaganol structure of Rm space group. The compound was annealed at 700 °C and 800 °C for 24 h. The discharge capacities obtained was 143 mAhg-1 in the first cycle for both materials. The voltage range was between 2.5 to 4.2 V. The 30th cycle, however, revealed that the material annealed at 700 °C shows the better performance. The capacity fading is only about 14% compared to 17% for the 800 °C sample. This implies that LiMn0.3Co0.3Ni0.3Ti0.1O2 material is sensitive to annealing temperature. They exhibited good specific capacity values and looked promising for Li-ion battery application.
