| titleOfInvention | Polyolefin microporous membrane, battery separator, and battery |
| abstract | The present invention provides a polyolefin microporous membrane capable of preventing the deterioration of the air permeability of the separator caused by the press working under high pressure in the production process of the battery, and having excellent compression resistance. In addition, it is possible to provide a battery having excellent cycle characteristics using the polyolefin microporous membrane of the present invention. A polyolefin microporous membrane having a change in air resistance after heating and compressing for 5 minutes at a temperature of 90° C. and a pressure of 5.0 MPa is 50% or less, and the membrane of the polyolefin microporous membrane before heating and compressing When the thickness is set to 100%, the film thickness change rate after heating and compression for 5 minutes at a temperature of 90° C. and a pressure of 5.0 MPa is 10% or less. |
