Collection: Battery Separators

Compare battery separator films, membranes and pre-cut discs for laboratory cells. Options include PP, PE, PP/PE/PP trilayer, ceramic-coated, cellulose and glass-fiber materials.

Choose by thickness, roll width or disc diameter, porosity, coating structure and electrolyte wettability. Suitability for lithium-ion, sodium-ion, lithium-sulfur or supercapacitor research depends on the specific separator and test conditions; consult each product's specifications. Check that the separator dimensions and compressed thickness suit your electrodes, cell hardware and assembly method, and compare pack quantities before purchase.
