Abstract
A porous composite material for diaphragms for high-output electrochemical cells such as lithium cells. The material is a layered structure of fluoropolymer and polyolefin that provides a shut-down capability that safeguards against dangerous failure of the cell, such as a rupture or fire that may result from a short-circuit or other high-rate electric discharge.
