Polyethylene (PE) Lithium-Ion Battery Separator Roll – Wet Process, 20 µm (500 m or 1500 m × 60 mm) for Li-ion Cell Research

https://www.s4r.fr/web/image/product.template/92/image_1920?unique=ce393d6

High-quality microporous polyethylene (PE) lithium-ion battery separator roll manufactured using the wet process, designed for Li-ion cell assembly, electrode stacking, and laboratory-scale battery development.

The separator provides high porosity (44 ± 5%), low Gurley air resistance (230 ± 60 s/100 ml), and excellent mechanical strength, making it suitable for pouch cells, cylindrical cells, and coin cell prototyping.
