摘要：
A positive electrode for a lithium secondary battery obtained by bonding a positive electrode-active material, a conductive material, and a current collector with a carbon which has a graphitization degree expressed by a peak intensity ratio, i.e. the ratio of peak intensity at 1360 cm−1 to peak intensity at 1580 cm−1 in the argon laser Raman Spectrum, of 1.0 or lower.
