Negative electrode for nonaqueous electrolyte secondary batteries and nonaqueous electrolyte secondary battery including the same

Abstract

A negative electrode for nonaqueous electrolyte secondary batteries includes a negative electrode core member and a negative electrode mixture layer attached to the negative electrode core member, wherein the negative electrode mixture layer contains negative electrode active material particles with a graphite structure and a binder, the mixture density of the negative electrode mixture layer is 1.5 g/cm3 to 1.8 g/cm3, the ratio I(002)/I(110) of the diffraction intensity 1(002) of the (002) plane to the diffraction intensity I(110) of the (110) plane satisfies 60≦I(002)/I(110)≦120 as determined by measuring the negative electrode mixture layer by an X-ray diffraction method, the amount of particles with a size of 1 μm to 10 μm in the particle size distribution of a crushed product of the negative electrode mixture layer is 12% to 25% by volume.
