| titleOfInvention | Battery separator and preparation method thereof, lithium ion battery and electric vehicle |
| abstract | The invention relates to the technical field of battery materials, and discloses a battery separator and a preparation method thereof, a lithium ion battery and an electric vehicle. The battery separator includes a polymer fiber layer, wherein the polymer fiber layer contains polymer fibers, and the polymer fibers contain a cross-linked polymer composed of modified polyethylene terephthalate. Obtained by crosslinking glycol ester and acrylate polymer; wherein, the modified polyethylene terephthalate contains hydroxyl and/or carboxyl groups, or the modified polyethylene terephthalate tape There are carbon-carbon double bonds. The battery separator provided by the invention has good heat-resistant shrinkage performance, more and uniformly distributed pores, good air permeability, and can meet the safety and electrochemical performance requirements of lithium batteries. |
