Abstract:
A cathode material for a lithium-ion secondary battery including: granulated bodies in which primary particles are aggregated, wherein an average particle diameter of the granulated bodies is 0.90 μm or more and 2.00 μm or less, particle diameters of 90% or more of the granulated bodies are 0.25 μm or more and 3.50 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 said plurality of diameters is considered as a particle diameter of each of the granulated bodies.

Claim (Index 6):
The cathode material for a lithium-ion secondary battery according to  claim 1 ,\n wherein the cathode material has 35.0% or more and 39.0% or less of an electrode porosity of a cathode for a lithium-ion secondary battery, wherein the electrode porosity is obtained by: adding the cathode material, polyvinylidene fluoride shown by PVdF, and acetylene black shown by AB to N-methyl-2-pyrrolidinone shown by NMP so that a mass ratio (the cathode material:AB:PVdF:NMP) in paste is 36:2:2:60, mixing the components to form a mixture, kneading the mixture using a kneader in a dispersion mode for 10 minutes at a revolution rate of 2,000 rpm and then in a defoaming mode for five minutes so as to prepare a cathode material paste, applying the cathode material paste to a surface of a 30 \u03bcm-thick aluminum foil having a flat surface so as to form a coated film, drying the coated film at 120\u00b0 C. for 12 hours in a vacuum atmosphere to form a cathode mixture layer on the surface of the aluminum foil, cutting the cathode mixture layer to a coating width of 3.5 cm, pressurizing the cathode mixture layer using a roll press machine having a load management function at a gap of 45 \u03bcm, a linear pressure of 7 t/250 mm, and a feeding rate of 0.5 m/min to generate a cathode for a lithium-ion secondary battery, and evaluating an electrode porosity of the cathode for a lithium-ion secondary battery.
