| titleOfInvention | Manufacturing method of multilayer polyolefin separator for lithium secondary battery and multilayer polyolefin separator for lithium secondary battery manufactured therefrom |
| abstract | The present invention relates to a method for manufacturing a multilayer polyolefin separator for a lithium secondary battery and a multilayer polyolefin separator for a lithium secondary battery manufactured therefrom. More specifically, the separator of the layer B / A / B has a high short-circuit temperature and a high temperature. The present invention relates to a method for preparing a multilayer polyolefin separator for a lithium secondary battery with improved membrane strength, and a multilayer polyolefin separator for a lithium secondary battery prepared therefrom. To this end, the method for preparing a multilayer polyolefin separator for a lithium secondary battery according to the present invention easily mixes a vinylidene fluoride-based polymer with a polyolefin using a compatibilizer, and a mixture thereof with polyolefin-vinyl together with liquid paraffin. Forming a layer A of a polymer form of lithium fluoride series, forming a layer B by kneading polypropylene and liquid paraffin, and forming the layer A and layer B into layers B / A / B. Coextrusion and casting, simultaneously biaxially stretching the cast sheet to prepare a separator, washing the biaxially stretched separator with a volatile solvent to remove liquid paraffin from the biaxially stretched separator, And heat-setting the washed biaxially stretched separator. |
