Abstract

A battery separator (16) having a thermal shutdown mechanism and exhibiting excellent mechanical properties and low electrical resistance includes a water-scavenging and/or acid-scavenging material having reactive functional groups (2) that chemically react with water or acid in a battery to remove the water or acid and thereby improve battery performance. The battery separator (16) preferably includes a first polyolefin providing mechanical integrity and a second polyolefin including the water-scavenging or acid-scavenging reactive functional groups (2). The battery separator (16) is preferably a microporous film (6) including a polymer matrix (4) throughout which the water-scavenging or acid-scavenging material is dispersed.
