Description
Li-Ion Battery Separator Film – 25 μm Thickness, 60 mm Width, 500 m Roll
Our Li-Ion Battery Separator Film is engineered from high-purity polypropylene (PP) and serves a crucial function in lithium-ion battery cells by physically separating the anode and cathode to prevent internal short circuits. With a thickness of 25 μm (±2) and a width of 60 mm, this film is ideal for battery R&D, prototyping, and small-scale production runs.
It offers excellent mechanical strength, thermal dimensional stability, and consistent porosity, ensuring safe and reliable operation across a wide range of battery applications.
