    • Disclosed herein are a polyolefin microporous membrane of which surface is modified by a hydrophilic polymer, a surface modification method thereof and a lithium ion polymer battery including the surface-modified polyolefin microporous membrane as a separator.The polyolefin microporous membrane of which surface is modified by a hydrophilic polymer minimizes membrane distortion by employing plasma-induced coating method and also increase the membrane's mechanical strength and heat resistance. In addition, the polyolefin microporous membrane enhances the ability of impregnating an electrolyte solution by increasing polarity and surface energy on its surface through modification to hydrophilic surface, and enhances the adhesion between a separator and an electrode, between a separator and an electrolyte solution or gel polymer electrolytes. Further, the lithium ion polymer battery including the polyolefin microporous membrane of which surface is modified by a hydrophilic acrylic polymer as a separator has enhanced cycle life and rate capability.
    • 本发明公开了一种聚烯烃微孔膜,其表面被亲水性聚合物,其表面改性方法和包含表面改性聚烯烃微多孔膜的隔离器的锂离子聚合物电池改性。 表面被亲水性聚合物改性的聚烯烃微多孔膜通过采用等离子体诱导的涂覆方法使膜变形最小化,并且还增加膜的机械强度和耐热性。 此外,聚烯烃微多孔膜通过改善亲水性表面而增加其表面上的极性和表面能,从而提高了电解质溶液的浸渍能力,并且增强了隔板与电极之间,隔膜与电解质溶液或凝胶之间的粘合性 聚合物电解质。 此外,包括其表面被亲水性丙烯酸类聚合物改性为隔膜的聚烯烃微多孔膜的锂离子聚合物电池具有增强的循环寿​​命和速率能力。
