METHOD OF MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
A method of manufacturing a nonaqueous electrolyte secondary battery includes: constructing a nonaqueous electrolyte secondary battery including an electrode body and an electrolytic solution, the electrode body including a negative electrode, and the electrolytic solution containing a nonaqueous solvent and a negative electrode film forming agent having a decomposition voltage that is lower than a decomposition voltage of the nonaqueous solvent; performing first charging of the nonaqueous electrolyte secondary battery at a voltage that is equal to or higher than the decomposition voltage of the negative electrode film forming agent and lower than the decomposition voltage of the nonaqueous solvent and at −30° C. to 0° C.; and performing second charging of the nonaqueous electrolyte secondary battery at a voltage that is equal to or higher than the decomposition voltage of the nonaqueous solvent and at a temperature of 25° C. or higher and lower than a boiling point of the electrolytic solution. |
