| titleOfInvention | Micropore separation membrane and its manufacturing method of bidrectional tensile coating for lithium ion batteries |
| abstract | The present invention discloses a bidirectional tensile coating micropore separator for a lithium ion battery and a method for manufacturing the same. The present invention directly proceeds the online coating process after the microporous membrane tensioning process, and allows the solvent in the coating membrane to volatilize through the drying shaping step to form a uniform and stable micropore separation membrane, thereby achieving the following invention effects. (1) Through the design of a special manufacturing method, the membrane hole maintains relatively high stability in the shaping step, and the stability of the coating is ensured. The coating film produced by the present invention has the characteristics of uniform aperture and high peel strength. (2) By submitting the online coating method to change the hole structure of the coating film, the adhesive strength between the coating layer particles and the base film is improved, thereby improving the peel strength of the film. (3) By coating the slurry before shaping and curing the surface hole structure, the refractive index of the film is lowered to obtain a micropore separator with relatively high battery circulation efficiency, and in this way, the production efficiency is improved and the cost is lowered. |
