Advanced Filtration Solutions for Lithium Battery Separators

Lithium battery separators play a critical role in preventing short circuits and ensuring battery performance. To achieve the required cleanliness, quality and consistency during manufacturing, separator materials and process fluids must be carefully filtered.

Pall provides filtration technologies that support battery separator production by helping manufacturers maintain process quality throughout key stages of manufacturing.

The battery separator manufacturing process requires exceptional material purity and consistency. Pall’s proven polymer melt filter technology ensures chemical companies supply high-quality polymeric separators to EV battery cell manufacturers. Purification steps include filtration of the molten polymer prior to film formation and filtration of various other additives and coatings used in the process.  A process schematic for the separator film production process identifying the purification steps, is shown below. The diagram below illustrates where filtration supports key stages of battery separator production, helping manufacturers maintain process consistency and product quality.
