| titleOfInvention |
Polyolefin microporous membrane, production method thereof, separator for non-aqueous electrolyte secondary battery, and non-aqueous electrolyte secondary battery |
| abstract |
The present invention provides a microporous membrane having an excellent balance of temperature characteristics, shrinkage characteristics, permeability, and strength, and thereby realizes a separator for a non-aqueous electrolyte secondary battery and a non-aqueous electrolyte secondary battery, having excellent performance and excellent safety. A polyolefin microporous membrane having; n a temperature difference not less than 7.2° C. between a shutdown shrinkage temperature and a maximum shrinkage temperature in a TD measured by TMA; n a shrinkage rate difference less than 25% between a shutdown shrinkage rate and a maximum shrinkage rate in the TD; n a pin puncture strength at a membrane thickness of 16 μm being not less than 400 gf; and n a ratio of pin puncture strength to air permeation resistance at a membrane thickness of 16 μm being from 2.0 to 4.0 (gf/(sec/100 cc)). |
