Process for producing lithium-cobalt composite oxide |
| abstract |
A mixture of a cobalt compound and a lithium compound is calcined at a temperature of 250 DEG C. to 1,000 DEG C., where said cobalt compound has a cobalt content of 68.5+/-6% by weight, its composition is substantially represented by a formula HxCoOy provided that 0</=x</=1.4 and 1.3</=y</=2.2, the half value width of a diffraction peak showing a maximum intensity in the neighborhood of 2 theta =36-40 degrees in X-ray diffraction using CuK alpha as a radiation source is greater than 0.31 degrees, and the relation between the cobalt content and the half value width is represented by the following formula: Half value width (degrees)>/=7.5-0.1x(Cobalt content) (% by weight). This provides an inexpensive and simple process for producing a lithium-cobalt composite oxide having uniform crystals, and a high-performance electrode active material for use in lithium secondary cells in high capacity and excellent in the charging-discharging cycle characteristics. |
