Battery separators for prismatic, pouch or round cells
Battery separators are porous membranes that separate the anode and cathode in battery cells – whether round, prismatic, or pouch cells. The separator prevents direct contact between the two electrodes while allowing ions to pass through. This ensures that the battery can work without short-circuiting.
Expert voice
”The demand for energy storage solutions will continue to grow, driven by the increasing adoption of renewable energy sources and electric vehicles. This will create new opportunities for battery separators, particularly in grid-scale storage and residential energy systems.”

Pasting material for lead-acid batteries
We complement our range of battery separators with a pasting material solution for lead-acid batteries. Pasting material is a vital component of lead acid batteries.
The material's refined porosity supports high battery performance and is optimized to integrate seamlessly into customers' processes. It adds mechanical strength during plate processing and improves long-term performance. The material adheres optimally to the lead paste and remains bonded to the plate surface throughout its cyclelife. It is resistant for acid degradation, preventing gap formation or compression loss.
