Layered structure Li[Co1/3Mn1/3Ni1/3] O2 was prepared by a spray drying method and characterized by means of x-ray diffraction and charge-discharge cycling. The hexagonal lattice parameters obtained for samples sintered at 800°C are a = 2.863Å and c- 14.244 A. The intensity ratio of the (003) to (104) peaks in the XRD pattern is 1.21. A discharge capacity of 154 mAh/g can be obtained in the range of 2.5-4.3 Vat a specific current of 30 mA/g, and the rechargeable capacity for samples sintered at 800°C is more than 140 mAh/g. Compared to the LiCoO 2 electrode, the Li[Co1/3Mn1/3Ni 1/3]O2 electrode has a comparatively high rate capability, so that Li[Co1/3Mn1/3Ni1/3]O2 is a promising candidate to replace LiCoO2 as the cathode material for lithium-ion batteries.
