Title:
MANUFACTURING METHOD OF CATHODE MIXTURE AND CATHODE MIXTURE OBTAINED USING IT
Document Type and Number:
Japanese Patent JP2010067499
Kind Code:
A
Abstract:

To provide a manufacturing method of cathode mixture capable of making a high-output battery standing practical use, for a lithium secondary battery using inorganic solid electrolyte.

A cathode active material and inorganic solid electrolyte are put under mechanical milling treatment, through which the cathode active material and the inorganic solid electrolyte are endowed with an energy of 50 to 700 kJ per 1 kg. With this treatment, dispersion of mixture particles is enhanced, and an excellent ion conduction path is obtained to have output characteristics of the battery improved.
