Battery Pack Liquid Absorbers for climate and moisture management in lithium-ion battery packs

Battery packs are the core components of mobile and stationary lithium-ion energy storage systems. They are used in automotive and industrial applications. The performance and lifespan of these components are largely responsible for the efficiency of the entire energy storage system. Moisture inside the packs can significantly impair both function and lifespan. Battery Pack Liquid Absorbers from Freudenberg Performance Materials prevent this by reliably absorbing liquids inside the battery pack.

The challenge: condensate and leaking coolant

Liquids leaking inside a battery pack can result from various causes. One major factor is ambient humidity: air enters the battery pack, and moisture condenses inside the cooled system. Another issue is coolant leakage from the cooling system. In both cases, the absorbent fleece functions as a safety system, reliably capturing and retaining condensate and leaking coolant. 

Absorbent pads reliably manage moisture and make electric vehicles safer 

Freudenberg Performance Materials has developed its Battery Pack Liquid Absorbers as absorbent pads that can reliably capture and retain large volumes of liquid. The modular design enables scalable absorption capacity – limited only by the available space. Customer-specific geometries can even be implemented thanks to the flexible material.

Stable, long-term protection of the battery pack

The pads offer a durable solution for managing climate and moisture inside battery packs. The fleece material quickly absorbs condensate and stores it effectively. Even in an emergency, leaking coolant is quickly absorbed and reliably retained.
