A battery separator is a crucial component in batteries, particularly in rechargeable lithium-ion batteries, which are commonly found in numerous devices such as smartphones, laptops, and electric vehicles.  Li-ion batteries have the highest demand in the world due to their high charging capacity, and extended battery life requirements. The separators are thin porous polymeric membranes that separate the positive and negative electrodes, allowing the flow of lithium ions while charging the batteries. For the separators to function optimally, it is important that the polymeric materials they are made of are filtered prior to their formation. These high-performance filtration solutions are used widely across many different fabrication processes to achieve the separators required technical specifications, cleanliness quality, and uniformity required for EV battery cell separators.

TIANHONG provides advanced filtration technologies that support the production of these essential components, helping manufacturers meet the growing demand for reliable, high-capacity energy storage systems.
