ABSTRACT:
A trilayer shutdown battery separator is provided having two strength layers sandwiching a shutdown layer that is made by a particle stretch method. The preferred method of making such a trilayer separator comprises: making microporous strength layers; forming a microporous shutdown layer by a particle stretch method; and bonding two microporous strength layers and one microporous shutdown layer into the trilayer battery separator wherein the first and third layers are strength layers, and the second membrane is a microporous shutdown layer made by a particle stretch method.
