    摘要: A method of making a trilayer, shutdown battery separator has the following steps: extruding a polyethylene precursor; extruding a polypropylene precursor; forming a trilayer precursor, the trilayer precursor having the polyethylene precursor sandwiched between two polypropylene precursors; bonding the trilayer precursor; annealing the trilayer precursor; stretching the trilayer precursor; and forming thereby the battery separator.
