  • Patent number: 7374843
    Abstract: The invention relates to a microporous membrane, which is provided with high safety even under a condition that the interior temperature of a battery becomes high, and which has high permeability and high mechanical strength at the same time. The polyolefin microporous membrane is characterized by a membrane thickness of 5 to 50 ?m, a void content of 30 to 60%, a gas transmission rate of 40 to 300 sec/100 cc/20 ?m, a piercing strength of not less than 2.5 N/20 ?m and a break through temperature of not lower than 110° C. The separator in accordance with the present invention is used to exhibit high safety under a high temperature condition as well as high permeability, and therefore it is particularly useful as a separator for miniaturized high capacity batteries of a non-aqueous electrolytic solution type.

  • Publication number: 20070148552
    Abstract: Disclosed is a microporous membrane made from a polyolefin wherein the thickness is 1-30 ?m, the porosity is 30-60%, the air permeability is 50-250 sec/100 cc, the puncture strength is 3.5-20.0 N/20 ?m, the maximum pore diameter determined by a bubble point method is 0.08-0.20 ?m, and the ratio between the maximum pore diameter and the average pore diameter (maximum pore diameter/average pore diameter) is 1.00-1.40. Since this microporous membrane made from a polyolefin is highly safe while maintaining a high permeability, it is useful especially as a separator for recent small-sized, high-capacity nonaqueous electrolyte batteries.
