Freudenberg Performance Materials has developed Battery Pack Liquid Absorbers for lithium-ion batteries. Battery packs are the core elements of mobile and stationary lithium-ion energy storage devices. They are used in automotive and industrial applications.
The performance and lifespan of these components are mainly responsible for the efficiency of the systems. Any moisture inside the packs can considerably damage the lifespan.
Battery Pack Liquid Absorbers from Freudenberg prevent this by reliably absorbing liquids inside battery packs. Liquids leaking inside a battery pack can have a variety of causes.
The humidity of the air is one major issue. Air enters into the battery pack, and moisture condenses inside the cooled pack. Another problem is coolant leaking out of the cooling system. In both cases, the absorbing fleece acts as a safety system to capture and retain condensate and leaking coolant reliably.
Freudenberg developed its Battery Pack Liquid Absorbers as absorbent pads that can reliably take up and store large volumes of liquid. The modular design allows for scaling the absorption capacity, which is limited only by the available space.
Customer-specific geometries can even be implemented thanks to the flexible material. The pads are a long-lasting solution for climate and moisture management in battery packs. The fleece material quickly takes up condensate and stores it effectively.
Even in an emergency, leaking coolant is quickly absorbed and reliably retained.
