The great majority of vehicles on the road today are fueled by conventional fuels, but make no mistake: electric vehicles (EVs) are rapidly gaining ground. According to Forbes, 2 million electric vehicles were sold globally in 2018, up 400 percent from 2015. Personal transportation is gradually becoming more reliant on energy. Furthermore, the broad and expanding range of infotainment and navigation devices available in modern automobiles implies that today’s vehicles have extraordinary electrical requirements.
As a result, EV batteries must supply more power, more cycles, and a longer lifetime if electric vehicles are to thrive. Because of its high power density and charging efficiency, lithium-ion (Li-ion) battery packs are still the preferred power source for electric vehicles. These batteries, on the other hand, have short operational lives and rapidly degrade with age, concerns that are compounded by harsh automobile settings. We have the best Electronics tapes in the market.
Dielectric foams can accommodate the battery cells’ dimensional variations and variances while yet providing enough pressure to prevent misshaping and disconnections. The foam has a springy feel to it, yet it is actually better than a spring. The higher the potential return energy of a spring, the more it deflects. However, compression force deflection, a feature of foams, can be tailored to produce the same, constant return energy throughout a wide range of compression quantities (CFD). Springs are thermally and electrically conductive, and they can cause battery hard spots.
The battery’s foam cushioning has a remarkable compression set, which refers to a material’s capacity to withstand permanent deformation under compressive stresses. Other alternative materials options, such as other elastomers, will not survive the performance of specifically built polyurethane- and silicone-based foams, which will outlast the battery’s lifespan. Another benefit is that foam has a significantly wider operating temperature range than most other rubbers. The safety of the battery components is paramount, and foam materials provide valuable protection. Best RFID adhesive can be found here.
Because of the complexities of compression pads, specifically developed microcellular polyurethane and silicone are the best materials. High-performance polyurethane foams work in temperatures ranging from -35 to 70 degrees Celsius and can be easily customized in terms of size, density, and surface characteristics. The Norseal PF100, Norseal PF40, and Norseal PF20 Series from Saint-Gobain Tape Solutions include specifically developed polyurethane compression pads.
High-performance silicone foams, with an operational temperature range of -51°C to 204°C, are the superior choice for applications that require a wider temperature range. With a UL94 rating of V-0, these Silicone foams also help to limit the threat of thermal runaway due to their low smoke generation and minimal flame spread features. Saint-Gobain offers Norseal F12 and Norseal F20 to meet these requirements.
Throughout a wide range of compressive stresses, all Norseal devices supply consistent, reliable pressure (CFD) to the battery components.

Compressive pads from Saint-Gobain come in a variety of CFD values, making them appropriate for a wide range of applications. Materials for compressive pads can be supplied with or without an adhesive layer. Lithium-ion batteries are critical to electric vehicles and will continue to be so for the foreseeable future. Every feasible improvement in battery efficiency must be achieved to accelerate EV growth with current technologies. Manufacturers are brainstorming new ways to extend battery life, and Saint-expertise Gobain’s and engineering will be crucial in these developments. For tomorrow’s EV batteries, Saint-Gobain is already developing the next generation of compression pad materials.
