| titleOfInvention | Polyolefin microporous membrane and method for producing the same |
| abstract | (57) Abstract: The structure of a battery separator, in particular, the roughness and porosity of the surface of the film in contact with the electrode are controlled to improve the effective cross-sectional area of the electrode and to prevent electrolysis. A polyolefin microporous film capable of improving battery characteristics by improving the amount of retained liquid, forming an electrolyte-rich layer, and improving the movement speed of lithium ions between electrodes during charging and discharging, and a method for producing the same. provide. (1) A microporous polyolefin membrane having a weight average molecular weight of 5 × 10 5 or more or a polyolefin composition thereof and having a surface smoothness of 50,000 seconds or less and a surface porosity of 40% or more. And (2) 10 to 80% by weight of the polyolefin or its composition A method for producing a microporous polyolefin membrane, which comprises cooling a solution containing 90 to 20% by weight of a solvent to form a gel-like molded article, and heating and stretching the gel-like molded article under a temperature-lowering condition. |
