摘要：
The invention relates to microporous membranes comprising polymer and having well-balanced permeability, shutdown temperature, and pin puncture strength. The invention also relates to methods for making such membranes, and the use of such membranes as battery separator film in, e.g., lithium ion secondary batteries. The membrane has a shutdown temperature
