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 1):
A cathode material for a lithium-ion secondary battery, the cathode material comprising:\n 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\u2212b)/a) is 0.03 or more and 0.30 or less, 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, and the central particles are represented by general formula Li x Fe y M z PO 4  (here, M represents at least one element selected from the group consisting of Mg, Ca, Co, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, and rare earth elements, 0.95 x 1.10, 0.80 y 1.10, and 0.00 z 0.20).
