Title:
POLYOLEFIN MICROPOROUS MEMBRANE, PRODUCTION METHOD FOR POLYOLEFIN MICROPOROUS MEMBRANE, BATTERY SEPARATOR, AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/170289
Kind Code:
A1
Abstract:
The present invention provides a polyolefin microporous membrane and a production method therefor that make it possible to achieve a low shutdown temperature while keeping air resistance sufficiently low. When the temperature of this polyolefin microporous membrane is increased by differential scanning calorimetry (DSC) to 230℃ at a rate of 10℃/min., if the total heat of fusion (ΔHa11) is 100%, the fraction thereof that is the heat of fusion (ΔH
