Abstract

Spherical Li[Li_0.2Ni_0.2Mn_0.6]O₂ has been synthesized by a carbonate co-precipitation method. The Li[Li_0.2Ni_0.2Mn_0.6]O₂ with a phase-pure and well-ordered layered structure was synthesized by heat-treatment of a spherical (Ni_0.25Mn_0.75)₃O₄ precursor with LiOH·H₂O. The average particle size of the Li[Li_0.2Ni_0.2Mn_0.6]O₂ powders was approximately 20 μm and the size distribution was quite narrow due to the homogeneity of the (Ni_0.25Mn_0.75)CO₃. The Li[Li_0.2Ni_0.2Mn_0.6]O₂ electrode calcined at 900 °C delivered an initial discharge capacity of approximately 270 mAh g^-1 in the voltage range of 2.0-4.6 V. The differential scanning calorimetry (DSC) results for the Li[Li_0.2Ni_0.2Mn_0.6]O₂ prepared at 900 °C showed a major exothermic reaction at 270 °C.
