| titleOfInvention | Polyolefin laminated microporous membrane |
| abstract | [Problem] The present invention aims to improve the rupture resistance of the microporous membrane under high temperature without impairing the strength and porosity of the microporous membrane, and to achieve both device characteristics and safety of a power storage device including the microporous membrane as a separator. To do. [Solution] The microporous membrane for power storage device has a laminated structure, at least one layer of the laminated structure contains polyolefin having one or more functional groups, and the microporous membrane for power storage devices is stored in a power storage device Thereafter, (1) the functional groups are condensed with each other, (2) the functional group reacts with a chemical substance inside the power storage device, or (3) the functional group reacts with another kind of functional group to form a crosslinked structure. Further, the ratio MD/TD of the orientation ratio in the width direction (TD) to the machine direction (MD) when at least one layer containing the polyolefin is measured by wide-angle X-ray scattering satisfies 1.3 or more. |
