    Abstract: Disclosed herein is a microporous polyethylene film for a battery separator and a method of producing the same. The microporous polyethylene film is made from a resin composition. The resin composition comprises 100 parts by weight of a polyethylene composition including 10 - 50 wt% polyethylene having a weight average molecular weight of from 2 x 10 to less than 5 x 10 (component I) and 90 - 50 wt% diluent (component II), and 0 - 150 parts by weight of inorganic powder (component III). The film has a puncture strength of 0.20 N/mm or more and a gas permeability (Darcy's permeability constant) of 1 x 10 Darcy or more. The microporous polyethylene film has excellent physical properties, thus improving the performance and stability of a battery.

    Abstract: Disclosed is a microporous high density polyethylene film for a battery separator and a method of producing the same. The microporous high density polyethylene film includes high density polyethylene with a weight average molecular weight of 2x10 to less than 5x10 , containing 5 wt % or less molecule with a molecular weight of 1x 10 or less. The microporous high density polyethylene film has tensile strengths of 1, 100 kg/cm or more in transverse and machine directions respectively, a puncture strength of 0.22 N/D or more, a gas permeability (Darcy's permeability constant) of 1.3x 10 Darcy or more, and shrinkages of 5 % or less in machine and transverse directions, respectively. Particularly, the microporous high density polyethylene film has an excellent extrusion-compoundabiliy and stretchability and a high productivity, and can improve the performances and stability of a battery produced using the same.
