UL 2591 OUTLINE
UL Outline of Investigation for Battery Cell Separators
|Publication Date:||9 October 2018|
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.
