Abstract: A method for extracting electrolyte solution in lithium secondary battery includes (S1) freezing a secondary battery by impregnating in liquid nitrogen and then cutting it without disassembling; (S2) immersing the frozen cut secondary battery in an extraction solvent to extract an electrolyte solution contained in the battery; and (S3) calculating the total amount of the electrolyte solution with respect to the total size of the battery from the content of the extracted electrolyte solution, and then determining a ratio of total amount of the electrolyte solution to the content of the electrolyte solution used in manufacturing the secondary battery to obtain extraction efficiency. A system for extracting an electrolyte solution in a secondary battery is also provided.

Abstract: A substrate processing apparatus includes an outer bath, an inner bath in the outer bath, a chemical solution supply pipe in fluid communication with a portion of the outer bath, and an outer gas supply pipe in fluid communication with another portion of the outer bath. The outer bath includes an outer body providing an outer receiving space, and an outer door coupled to the outer body and configured to close the outer receiving space. An end of the outer gas supply pipe is located in the outer receiving space between the outer body and the inner bath, and a portion of the chemical solution supply pipe is located in the inner bath.
