Polyurethane foam, silicone foam, and Ethylene-Vinyl Acetate (EVA) foam are commonly used foams in EV battery manufacturing. Each type serves specific purposes, such as thermal, electrical, and shock absorption. What are some advancements in foam technology for EV batteries?
The performance of specially engineered polyurethane- and silicone-based foams will outlast the lifespan of the battery, which isn't true for other potential materials solutions such as other elastomers. Another advantage is foam's remarkable operational temperature range, much larger than most other rubbers.
This provides consistent, engineered return pressure, evenly across the battery. Foams are also resistant to common challenges of automotive environment – extreme temperatures, vibration and shock loads and chemical interactions.
Regarding EV battery production, foam ensures optimal performance and longevity. Foam is widely used as an insulation material within battery packs, protecting the cells from extreme temperatures and vibrations. This insulation not only enhances safety but also helps maximise energy efficiency.
Table 1 lists the foam pads used in this study. Polyurethane (PU) foam is the baseline material, designed to hold components of EV battery packs in place and to provide vibration isolation and cushion expansion and contraction of pouch cells during their service life.
But foams can be engineered to deliver the same, consistent return energy across a wide range of compression amounts, a property known as compression force deflection (CFD). Springs are also thermally and electrically conductive and can create hard spots in the battery.
