| 摘要 |
The present invention is a lithium secondary cell characterized in that a peak of 167-171 eV and a peak of 160-164 eV are present using XPS analysis (S2p) of sulfur in the surface of a negative electrode, the ratio (P169/P162) of the strength (P169) of the peak of 167-171 eV and the strength (P162) of the peak of 160-164 eV is within a range of 0.7-2Ø |
