Title:
非水電解液二次電池用正極およびそれを用いた非水電解液二次電池
Document Type and Number:
Japanese Patent JP4163410
Kind Code:
B2
Abstract:

To provide a positive electrode for a secondary battery and a nonaqueous electrolytic solution secondary battery wherein a better charge- discharge cycle property can be satisfied simultaneously while a superior high- capacity property of the nonaqueous secondary battery such as a lithium-ion secondary battery is being maintained.

In the positive electrode for the secondary battery wherein a positive electrode layer is formed by compressing a collector after coating and drying a positive electrode mix containing a positive electrode active material, this is the positive electrode for the secondary battery characterized in that the intensity ratio I(104)/I(003) of the diffraction peak intensity I(104) of (104) face with the diffraction peak intensity I(003) of (003) face is 0.005 or more and less than 0.025 in case X-ray diffraction having CuKα as the radiation source is carried out on the positive electrode layer surface.
