Abstract
The present disclosure provides a polymer separator and preparation method thereof, and a lithium-ion battery including the polymer separator and preparation method thereof. The polymer separator includes a porous substrate, a hydrophilic blocking layer, and a porous polar polymer bonding layer. The hydrophilic blocking layer is disposed between the porous substrate and the porous polar polymer bonding layer. Pore walls in the porous polar polymer bonding layer are provided with node structures.
