Synthesis of Li1.5Ni0.25Mn0.75O2.5 cathode material via carbonate co-precipitation method and its electrochemical properties

Lithium rich cathode materials with high specific capacity are considered as promising candidates for improving the energy density of lithium ion cells. In this paper, a Li-rich cathode material, Li1.5Ni0.25Mn0.75O2.5 with well-ordered layered structure is successfully synthesized using a simple carbonate co-precipitation method followed by calcination at 900 degrees C. The phase purity was studied by X-ray diffraction (XRD) and morphology was studied by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). SEM analysis of the material revealed cylinder-shaped particles with diameter in the range 100-350 nm. The electrochemical evaluation of the material reveals an initial specific capacity of similar to 240 mAhg(-1) at C/20 rate.
