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, Li_1.5Ni_0.25Mn_0.75O_2.5 with well-ordered layered structure is successfully synthesized using a simple carbonate co-precipitation method followed by calcination at 900 °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 ~240 mAhg⁻¹ at C/20 rate.

具有高比容量的富锂阴极材料被认为是改善锂离子电池能量密度的有前途的候选材料。本文采用简单的碳酸盐共沉淀法，然后在900°C下煅烧，成功合成了层序结构良好的富锂正极材料Li _1.5 Ni _0.25 Mn _0.75 O _2.5。通过X射线衍射（XRD）研究相纯度，并且通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）研究形态。对该材料的SEM分析显示直径为100-350 nm的圆柱状颗粒。该材料的电化学评估表明，初始比容量约为240 mAhg在C / 20速率下为^-1。
