Abstract:
A cathode material fora lithium-ion secondary battery which includes granulated bodies in which primary particles are aggregated, wherein an average particle diameter of the granulated bodies is 4.50 μm or more and 6.20 μm or less, and particle diameters of 90% or more of the granulated bodies are 1.00 μm or more and 11.00 μm or less, wherein particle diameters of the granulated bodies are evaluated such that 300 granulated bodies are randomly selected from a view of the granulated bodies using a scanning electron microscope, a plurality of diameters of each of the 300 granulated bodies that pass through a central point thereof are evaluated, and a maximum diameter selected from the plurality of diameters is considered as a particle diameter of each of granulated bodies.

Claim (Index 1):
A cathode material for a lithium-ion secondary battery which comprises granulated bodies in which primary particles are aggregated,\n wherein the primary particles are represented by general formula Li x A y M z PO 4  (here, A represents at least one element selected from the group consisting of Fe, Mn, Co, and Ni, 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<x\u22641.1 0.8\u2264y\u22641.1 and 0\u2264z\u22640.2) (supported by claim  4 , and x is amended such that x is greater than 0), surfaces of the primary particles are coated by a thermally decomposed carbonaceous film (supported by claim  3  and the paragraph 0074), the thickness of the carbonaceous film is 0.2 nm or more and 10 nm or less (supported by the paragraph 0030), wherein an average particle diameter of the granulated bodies is 4.50 \u03bcm or more and 6.20 \u03bcm or less, and particle diameters of 90% or more of the granulated bodies are 1.00 \u03bcm or more and 11.00 \u03bcm or less, wherein particle diameters of the granulated bodies are evaluated such that 300 granulated bodies are randomly selected from a view of the granulated bodies using a scanning electron microscope, a plurality of diameters of each of the 300 granulated bodies that pass through a central point thereof are evaluated, and a maximum diameter selected from the plurality of diameters is considered as a particle diameter of each of granulated bodies.
