Title:
Rechargeable battery
Document Type and Number:
Japanese Patent JP6135667
Kind Code:
B2
Abstract:
A secondary battery with a high capacitance retention rate associated with charge/discharge cycles is provided. This secondary battery is equipped with: an electrolytic solution that contains a lithium salt, a non-aqueous solvent capable of dissolving the lithium salt, and an additive; a positive electrode that contains a positive electrode active material into/from which lithium can be inserted/removed; and a negative electrode. A compound that has a peak in the 2,476eV to 2,479eV range of a sulfur K-edge X-ray absorption fine structure spectrum is formed on a surface of the positive electrode active material.
