These requirements cover short-term test procedures to be used for the evaluation of battery cell separators for use in lithium ion cells. These separators are intended to provide electrical insulation between the lithium-ion cell electrodes while still allowing for ion transport between the electrodes@ when filled with electrolyte. The test procedures covered in this outline provide information with respect to the physical@ mechanical@ thermal@ flammability and other properties of the battery cell separator under consideration.
