<p>PROBLEM TO BE SOLVED: To provide a method for obtaining a positive electrode material which has excellent conductivity and also can sufficiently enhance battery performance, while using an olivine type silicate compound.SOLUTION: A method of manufacturing a positive electrode material for a secondary battery is characterized in that secondary particles are formed by drying primary particles of an olivine type silicate compound obtained by hydrothermal reaction, composite particles are formed by mixing the obtained secondary particles and conductive carbon powder while applying a compressive force and shear force by dry process, and then, the obtained composite particles are calcinated at 200 to 300°C under an air atmosphere.</p> |
