| titleOfInvention | A kind of ultra-high molecular weight polyethylene lithium battery separator and preparation method thereof |
| abstract | The invention discloses an ultra-high molecular weight polyethylene lithium battery separator and a preparation method thereof. The lithium battery separator includes the following components by weight: ultra-high molecular weight polyethylene 20-40wt.%, pore-forming agent 60-80wt.%, and the pore-forming agent is composed of polyvinyl alcohol and glycerin; The lithium battery separator is prepared as follows: The ultra-high molecular weight polyethylene is put into the extruder together with polyvinyl alcohol and glycerin after the solid-phase grafting reaction, and is made by extrusion melting, casting, high-rate stretching, washing into holes, heat-setting, and winding. An ultra-high molecular weight polyethylene lithium battery separator. Using a water-soluble pore-forming agent composed of ultra-molecular-weight polyethylene with polar functional groups, polyvinyl alcohol, and glycerol as raw materials, the prepared diaphragm has the characteristics of good pore size consistency, high air permeability and high liquid absorption, and the preparation method is simple. It can be used in the field of forming and processing of high-end lithium battery separators. |
