Lithium-ion (Li-ion) batteries, the power source of choice for the new generation of electric, hybrid, and plug-in hybrid vehicles, require cushioning, sealing and vibration isolation that must perform reliably under tough conditions. Rogers’ suite of battery pad solutions is designed to provide designers with high-performance options that can withstand the stresses of fluctuating compression and temperature. PORON® polyurethanes and BISCO® silicone materials are designed to reliably hold a consistent force, keeping battery cells aligned, sealed from dust and fluid and isolated from the damaging effects of vibration.
Battery Pad cushions, or compression pads, used inside an EV pouch cell battery pack must be firm enough to hold components in place and compressible enough to withstand dimensional changes to the pouch cells over the life of the battery. Reliable compression set resistance (C-set) and stress relaxation performance over a broad range of temperatures and conditions is critical. Battery pads made from PORON polyurethane and BISCO silicone foams have a unique ability to produce a very consistent level of force across a range of compressions. PORON material pads and silicone battery compression pads enable the designer to predict the material’s behavior across varied dimensional tolerances.
Batteries also need to be packaged to absorb internal impact energy. Vibration must be managed both within the pack and between the pack and the vehicle. PORON polyurethane and BISCO silicone anti-vibration pads are proven solutions within the automotive industry, providing solutions as vibration dampeners and isolators. The C-set of these unique materials withstands collapse caused by the stresses of compression and temperature over time, extending the life of the battery by continuing to seal and absorb shock.
BISCO silicone foams are the solution of choice for sealing and protecting battery enclosures from potential damage caused by the elements and road debris. Gaskets fabricated from BISCO silicone material seal out water, dust and debris while providing exceptional temperature and UV resistance. PORON polyurethane material is designed to reliably hold a consistent force, keeping battery cells aligned, sealed from dust and fluid and isolated from the damaging effects of vibration.
