| titleOfInvention | Manufacturing method of flame retardant multicomponent separator for lithium secondary battery and separator prepared therefrom |
| abstract | The present invention relates to a method for preparing a flame retardant multicomponent separator for a lithium secondary battery and a separator prepared therefrom. More specifically, the present invention relates to an ion by increasing affinity, that is, adhesion to a vinylidene fluoride series, which is a component of a liquid electrolyte of a lithium secondary battery. The present invention relates to a method for preparing a flame retardant multicomponent separator for a lithium secondary battery having excellent thermal stability as well as further improving conductivity, and a separator prepared therefrom.n n n To this end, the first aspect of the present invention comprises the steps of mixing by using a compatibilizer (compatibilizer) in order to easily kneading the vinylidene fluoride-based polymer and polyolefin in the method for producing a flame-retardant multi-component separator for a lithium secondary battery, Mixing the flame retardant to provide excellent thermal stability in the mixing step, dissolving the mixture mixed in the mixing step with liquid paraffin, and dissolving the dissolved mixture in a polyolefin-vinylidene fluoride-based polymer sheet Extruding and casting to produce a microporous membrane, simultaneously biaxially stretching the cast sheet to produce a microporous membrane, and biaxially stretched microporous membrane with a volatile solvent to remove liquid paraffin from the biaxially stretched microporous membrane. Washing the biaxially elongated microporous; And heat-setting the membrane. |
