| titleOfInvention | High-flexibility lithium ion battery film and preparation method thereof |
| abstract | The invention discloses a high-flexibility lithium ion battery film and a preparation method thereof, wherein the battery film is prepared from the following raw materials, by weight, 67% -74% of a pore-forming agent, 25% -30% of ultrahigh molecular weight polyethylene, 0.1% -0.2% of polycarbonate, 0.1% -2% of random copolymerization polypropylene, 0.1% -0.2% of chlorinated polyethylene, 0.1% -0.2% of polymethyl methacrylate, 0.1% -0.2% of a dispersing agent, 0.1% -0.2% of reinforcing fibers, 0.1% -0.2% of colloidal silica, 0.1% -0.2% of a compatilizer, and 0.1% -0.2% of a crosslinking agent, wherein the dispersing agent is prepared from polyvinylpyrrolidone and methylnaphthalene. When the ultrahigh molecular weight polyethylene and the white oil are mixed, polycarbonate, polypropylene random copolymer, chlorinated polyethylene, polymethyl methacrylate, polyvinylpyrrolidone, reinforcing fiber, colloidal silica, a compatilizer and a crosslinking agent are added at the same time for mixing, and the mixture is longitudinally and transversely stretched to finally obtain the effect of the lithium battery diaphragm with obvious crosslinking, a complex three-dimensional space structure and a high-tortuosity pore structure. |
