Method and system for extracting electrolyte in lithium secondary battery |
| abstract |
The present invention relates to a method for extracting an electrolyte solution in a secondary battery and a system therefor, the method comprising the steps of (S1) immersing a secondary battery in liquid nitrogen to freeze it and then cutting it without decomposition; (S2) extracting the electrolyte contained in the battery by putting the freeze-cut secondary battery in an extraction solvent; and (S3) calculating the total amount of the electrolyte for the entire size of the battery from the content of the extracted electrolyte, and then calculating the extraction efficiency by comparing it with the content of the electrolyte used in manufacturing the secondary battery. |
