    摘要: An electrode for non-aqueous electrolyte secondary batteries includes a current collector having principal surfaces facing each other and an active material layer which contains an active material, a binder, and a conductive material and which is placed on at least one of the principal surfaces of the current collector. The sum of the volume of the active material per unit area of the current collector and the volume of the conductive material per unit area of the current collector is 9.70×10−2 cm3/cm2 to 24.6×10−2 cm3/cm2, the volume of the active material being calculated from the average particle size D50 of the active material, the volume of the conductive material being calculated from the average particle size D50 of the conductive material. The pore volume of the active material layer per unit area of the current collector is 6.00×10−3 cm3/cm2 to 20.0×10−3 cm3/cm2.

    摘要: The positive electrode active material of the present invention contains an lithium iron phosphate compound having such diffraction peaks that diffraction peak intensity ratios at 2θ=17.2±0.5°, 2θ=20.8±0.5° and 2θ=25.6±0.5° are from 29 to 37, from 70 to 80 and from 85 to 94, respectively, when the diffraction peak intensity at 2θ=35.6±0.5° is deemed as 100 in a powder X-ray diffractometry using Cu-Kα ray as a radiation source. It becomes possible to provide a positive electrode active material that provides higher rate property and discharge capacity, and a positive electrode and a non-aqueous electrolyte secondary battery using the positive electrode active material.
