Fabrication and Application of Organic/Inorganic Hybrid Thin Films on the Pore Wall of Microporous Polyethylene Separator

Polyolefin materials,such as polyethylene and polypropylene,are the most widely used sep-arators materials in lithium ion batteries due to low cost,proper pore structure,good mechanicalstrength and favorable thermal shutdown property.However,the major disadvantages lie in their intrinsically hydrophobic siuface character。
