Document Type and Number:
Japanese Patent JP2016027548
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery that can suppress side reaction under charging and storage.SOLUTION: A nonaqueous electrolyte secondary battery comprises a positive electrode, a negative electrode and nonaqueous electrolyte containing nonaqueous solvent. Lithium fluoride (LiF) and a sulfur (S) component are fastened on the surface of the positive electrode and the surface of the negative electrode, respectively. The nonaqueous solvent contains at least fluorinated methyl propionate (FMP), and the occupation rate of fluorine-based solvent in the total weight of the nonaqueous solvent is not less than 55 wt.%.SELECTED DRAWING: Figure 1
