Document Type and Number:
Japanese Patent JP3019421
Kind Code:
B2
Abstract:
A nonaqueous-electrolyte secondary cell is disclosed which comprises a positive and negative electrode (1,2) and nonaqueous electrolyte. Each of the negative and positive electrode is formed of electrode mix layer comprises a binding agent and active material carrier or active material. The electrodes are thus formed to satisfy the intensity ratio (I1/I2) of a first peak (P1) near a diffraction angle of 17.7 DEG to a second peak (P2) near a diffraction angle of 18.5 DEG in an X-ray diffraction pattern obtained with the Cuk alpha radiation for the electrode mix layer is from 0.3 to 0.6.
