Abstract:
A cathode material for a lithium-ion secondary battery including: active material particles including central particles represented by general formula LixAyDzPO4 (here, A represents at least one element selected from the group consisting of Co, Mn, Ni, Fe, Cu, and Cr, D represents at least one element selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, and Y, 0.9<x<1.1, 0<y≤1, 0≤z<1, and 0.9<y+z<1.1) and a carbonaceous film that coats surfaces of the central particles, wherein, when a mixture of the active material particles, a conductive auxiliary agent and a binder in which a mixing ratio thereof is 94:1:5 in terms of a mass ratio is dissolved in a solvent to form paste having a total solid content amount of 45% by mass, a viscosity of the past is 5,000 mPa·s or less at a shear rate of 4.0 [l/s].

Claim (Index 1):
A cathode material for a lithium-ion secondary battery comprising:\n active material particles including central particles represented by general formula Li x A y D z PO 4  (here, A represents at least one element selected from the group consisting of Co, Mn, Ni, Fe, Cu, and Cr, D represents at least one element selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, and Y, 0.9<x<1.1, 0\u2264z<1, and 0.9<y+z<1.1) and a carbonaceous film that coats surfaces of the central particles, wherein the average primary particle diameter of the cathode material is 10 nm or more and 400 nm or less (supported by the paragraph 0032), the BET specific surface area of the cathode material is 5 m 2 /g or more and 25 m 2 /g or less (supported by  claim 3 ), an amount of carbon forming the carbonaceous film is 0.1 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the central particles (supported by  claim 3 ), when a mixture of the active material particles, a conductive auxiliary agent and a binder in which a mixing ratio thereof is 94:1:5 in terms of a mass ratio is dissolved in a solvent to form cathode material paste having a total solid content amount of 45% by mass, a viscosity of the past is 5,000 mPa\u00b7s or less at a shear rate of 4.0 [l/s], the shear rate is measured at a temperature of 25\u00b0 C. (supported by the paragraph 0194), the binder resin is a polytetrafluoroethylene resin, a polyvinylidene fluoride resin or fluorine rubber (supported by the paragraph 0103), the conductive auxiliary agent is at least one selected from the group consisting of particulate carbon, vapor-grown carbon fiber and fibrous carbon (supported by the paragraph 0106).
