Abstract:
A cathode material for a lithium-ion secondary battery, the cathode material including: secondary particles which are granulated active material particles including central particles and a carbonaceous film that coats surfaces of the central particles, wherein a granulated body breakage degree ((a−b)/a) of the secondary particles is 0.03 or more and 0.30 or less, and the granulated body breakage degree is calculated based on a relative particle amount a, at which a maximum peak is shown in a particle size distribution of the secondary particles, and a relative particle amount b, at which a maximum peak in a particle size distribution of the secondary particles is shown after a dispersion treatment of the secondary particles is performed using a homogenizer.

Claim (Index 8):
A method for manufacturing the cathode material for a lithium-ion secondary battery according to  claim 1 , the method comprising:\n manufacturing central particles and/or a precursor of the central particles; preparing a slurry by dissolving or dispersing an organic compound and at least one kind of central particle raw material, which is selected from the group consisting of the central particles and the precursor of the central particles, in water; and drying the slurry to generate dried substance and calcinating the obtained dried substance in a non-oxidative atmosphere, wherein, in the preparing of the slurry, a median diameter of the central particles in a particle size distribution, which is evaluated after dispersion treatment is adjusted to 100 nm or more and 160 nm or less, and a ratio (median diameter/crystallite diameter) of the median diameter to a crystallite diameter, which is calculated from crystallite diameters of the central particles before the dispersion treatment, is adjusted to 1.00 or more and 2.10 or less.
