  • Patent number: 11367926
    Abstract: A coating slurry with high adhesion and high ionic conductivity, a preparation method thereof, and a lithium battery separator are provided. The coating slurry with the high adhesion and the high ionic conductivity includes: PEAE: 1 to 60 parts; a dispersing agent: 0.01 to 10 parts; a wetting agent: 0.01 to 15 parts; and a solvent: 100 parts. The PEAE can be evenly coated on a basal membrane to form a lithium battery separator, which solves the problem that pure PEAE cannot be directly and evenly coated on a separator. The PEAE is coated on the basal membrane for the first time to prepare the lithium battery separator, which ensures that the lithium battery separator has characteristics of the high adhesion and the high ionic conductivity.
