Method for puryfing collected nmp solution and manufacturing pvdf-nmp solution using it |
| abstract |
Disclosed is a method for purifying a recovered NMP mixture liquid which purifies impurities by lowering the pH of a recovered NMP mixture liquid by using an ion exchange resin column. According to the present invention, it is possible to remove the dye-induced non-volatile substances present in the recovered NMP mixed solution, thereby preparing purified NMP and NMP-PVDF solutions which can be reused as a lithium ion secondary battery material. |
