SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2017069014
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a secondary battery having excellent cycle characteristics.SOLUTION: In a secondary battery including a positive electrode 4 containing a positive electrode active material, a negative electrode 6 containing a negative electrode active material, and a nonaqueous electrolyte 9 containing a lithium salt and an organic solvent, the negative electrode active material is a titanium-containing oxide, and the organic solvent is a sulfone compound. Excellent cycle characteristics can be exhibited, even when a lithium manganese composite oxide is used as the positive electrode active material.SELECTED DRAWING: Figure 1
