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.

Separator including substrate, hydrophilic blocking layer, and polar polymer bonding with nodal structure, and method of preparing the same

A gel polymer composite electrolyte, a polymer lithium ion battery comprising the gel polymer composite electrolyte and methods of preparing the polymer lithium ion battery are provided. The gel polymer composite electrolyte is formed by swelling after a polymer membrane absorbs an electrolyte, wherein the polymer membrane is formed by thermocuring a polymer mixture comprising an acrylic emulsion, water and ammonia water, and the acrylic emulsion has a glass transition temperature ranging from about &#x2212;30&#xb0; C. to about 50&#xb0; C.
