Title:
Lithium secondary battery
Document Type and Number:
Japanese Patent JP6319089
Kind Code:
B2
Abstract:
The present invention provides a lithium secondary battery, wherein a peak at 167 to 171 eV and a peak at 160 to 164 eV are present in XPS analysis of sulfur on a negative electrode surface (S2p), and P169/P162 is in the range of 0.7 to 2.0 wherein the P169/P162 is the ratio between the intensity of the peak at 167 to 171 eV (P169) and the intensity of the peak at 160 to 164 eV (P162).
