LiCoO2 PARTICULATE MATERIAL, METHOD OF MANUFACTURING THE SAME, AND SECONDARY BATTERY USING THE SAME

Japanese Patent JP2013028517

A

To provide a LiCoO₂ particulate material in which the shapes of the particulate material are uniform as a whole in a certain direction, a method of manufacturing the LiCoO₂ particulate material, and a secondary battery using the LiCoO₂ particulate material as a positive-electrode active material.

A LiCoO2 particulate material includes a wire-shaped material and has a major peak equivalent to a (104) surface, based on XRD measurement. The method of manufacturing the LiCoO₂ particulate material includes: a step of preparing wire-shaped Co-containing precursor particulates; a step of bringing a Li source into contact with the wire-shaped Co-containing precursor particulates in flux and forming the LiCoO₂ particulate material containing a wire-shaped material; and a step of isolating and obtaining the resultant LiCoO₂ particulate material from the other components. A secondary battery uses the LiCoO₂ particulate material as a positive-electrode active material.
