As the automotive industry continues to advance, the need for more durable and performance-focused components grows. When it comes to vehicle battery systems, achieving lightweight, yet durable systems is essential to the development of both traditional and electrified vehicles.
Dupont’s adhesive solutions are utilised by battery manufacturers across the world due to their diverse characteristics; from providing high-temperature resistance, to protecting electronic components from moisture, chemicals and harsh external environments.
Overall, Dupont adhesives help manufacturers to:
- Improve battery performance/reliability
- Achieve lightweight bonds
- Reduce future repair costs and processes
- Optimise production line with less bonding solutions required
Specifically, the Dupont solutions which are explored in this article are the:
- BETAMATE series – designed for providing lightweight, flexible and strong structural bonding to similar and dissimilar substrates, including those in EV batteries.
- BETATECH series – designed to act as a thermal interface material (TIM), providing thermal conductivity and optimised temperature control in EV batteries.
- BETASEAL series – designed for efficiently sealing and filling gaps, including those in EV batteries.
- BETAFORCE series: designed for providing composite bonding and corrosion protection to battery elements, while maintaining design flexibility and sustainability.
