Abstract
A method of manufacturing a nonaqueous electrolyte secondary battery includes the following steps of: constructing a battery assembly using a positive electrode, a negative electrode, and a nonaqueous electrolytic solution containing a compound represented by a specific formula; and forming a film on a surface of the positive electrode by charging the battery assembly such that the compound is decomposed. In an embodiment, during the construction of the battery assembly, a content of the compound is adjusted to be 0.1 mass % or more with respect to 100 mass % of a total amount of the nonaqueous electrolytic solution.
Claims6
A method of manufacturing a nonaqueous electrolyte secondary battery, the method comprising:
- constructing a battery assembly using a positive electrode, a negative electrode, and a nonaqueous electrolytic solution containing a compound (I) represented by following Formula (I),
- wherein M1 and M2 each independently represent a hydrogen atom, an alkali metal atom, or an ammonium cation, and R1 and R2 each independently represent a hydrogen atom, a substituted or unsubstituted carboxyl group, or a substituted or unsubstituted alkyl group having 1 to 8 carbon atoms;
- and
- forming a film on a surface of the positive electrode by charging the battery assembly such that the compound (I) is decomposed.
A nonaqueous electrolytic solution used for a nonaqueous electrolyte secondary battery, the nonaqueous electrolytic solution comprising:
- a supporting electrolyte;
- a nonaqueous solvent;
- and
- a compound (I) represented by following Formula (I),
- wherein M1 and M2 each independently represent a hydrogen atom, an alkali metal atom, or an ammonium cation, and R1 and R2 each independently represent a hydrogen atom, a substituted or unsubstituted carboxyl group, or a substituted or unsubstituted alkyl group having 1 to 8 carbon atoms.
