Water condensation and potentially leaking coolants inside lithium-ion battery packs can significantly diminish their function and lifetime. Freudenberg Performance Materials developed its Battery Pack Liquid Absorbers to prevent such problems. The absorbent pads capture and reliably store unwanted liquids. With adjustable absorption capacity and custom geometries, Battery Pack Liquid Absorbers ensure long-lasting battery packs.

Battery packs are the core elements of mobile and stationary lithium-ion energy storage systems in automotive and industrial applications. The performance and lifetime of these components are largely responsible for the efficiency of the energy storage system. Moisture and liquids occurring inside the packs can considerably damage them. Here, the humidity of the air is one major issue. Air enters into the battery pack, and creates condensation inside the cooled pack. Another problem is coolants which may accidentally leak out of the cooling system. In both cases, Freudenberg´s Battery Pack Liquid Absorbers act as a safety system to reliably capture and retain condensate and leaking coolants.
