| titleOfInvention | A liquid crystal reinforced ultra-high molecular weight polyethylene lithium battery separator and preparation method thereof |
| abstract | The invention relates to a liquid crystal-enhanced ultra-high molecular weight polyethylene lithium battery separator and a preparation method thereof, comprising the following components by weight: ultra-high molecular weight polyethylene 45-75 wt %, ultra-high molecular weight polyethylene graft material 5-15 wt % ; Liquid crystal polymer 20 ~ 40wt%. Using ultra-high molecular weight polyethylene as the matrix material of the separator, liquid crystal polymer as the skeleton material, and ultra-high molecular weight polyethylene graft as the compatibilizer, the highly oriented liquid crystal polymer is uniformly dispersed in the separator through the blending extrusion process. During the high-rate stretching in the vertical and horizontal directions, the liquid crystal polymer is staggered in the vertical and horizontal directions to form a highly oriented network structure. Because the liquid crystal polymer has the characteristics of high strength, high heat resistance and high flame retardancy, it can comprehensively improve the performance of the diaphragm. , so as to achieve the purpose of improving the safety factor of lithium batteries. |
