Advanced Adhesives for EV Manufacture
As the global automotive industry transitions at pace and scale to more EVs in both passenger and commercial categories, pressure is mounting on manufacturers to incorporate faster charging, higher energy density batteries with improved lifetimes.
Achieving this transformation requires collaboration across the entire mobility ecosystem to advance battery technology, battery systems, vehicle electronics and charging infrastructure. Through advanced adhesive, sealing and thermal management technologies, Henkel is helping accelerate the future of electric mobility by enabling rapid co-innovation across the EV value chain.
Electric powertrains
“The shift from combustion engines to electric powertrains brings a different set of engineering challenges,” says Natasha Naidoo, Director Henkel Adhesives South Africa.
“Key EV components, such as the battery, power conversion and e-drive systems, must meet demanding requirements for safety, thermal management, performance, cost efficiency and circularity. Through close collaboration with OEMs, tier suppliers, and battery manufacturers, we help address these challenges globally with a broad portfolio of advanced material solutions.”
To satisfy consumer demand for increased vehicle range, faster charging speeds and more battery capacity, ‘behind the scenes’ technology is making these capabilities possible. Advanced adhesives, thermal interface materials, sealants and protective solutions play a critical role in helping batteries operate safely, protecting sensitive electronics and ensuring charging systems perform reliably under demanding conditions.
Heat a significant challenge
As battery performance requirements increase, so too does the importance of effective thermal management. Heat is one of the most significant challenges facing modern EV battery systems as poor heat dissipation can affect battery performance, charging efficiency, longevity and safety.
To tackle these challenges, Henkel has developed advanced thermal management solutions, including thermal gap fillers and thermally conductive adhesives that efficiently transfer heat away from critical components.
Thermal stability
These technologies help support faster charging, improve battery performance, enhance thermal stability and extend battery life, while enabling manufacturers to design increasingly compact and efficient battery systems.
“As battery technology continues to evolve, effective thermal management is becoming a key enabler of performance, safety and reliability. The ability to manage heat efficiently is essential not only for battery protection, but also for enabling the faster charging and higher energy densities that consumers increasingly expect,” Natasha points out.
Vehicle architecture
The EV industry is increasingly moving toward highly integrated vehicle platforms, with multiple functions such as propulsion, charging and power conversion being combined into compact ‘x-in-1’ systems.
These integrated architectures place greater demands on thermal performance, electrical insulation and component protection. Henkel’s advanced materials support critical components such as batteries, inverters, onboard chargers, DC-DC converters, electric motors and drive units, helping ensure reliable operation in increasingly compact and high-performance designs.
Design to testing
The success of electric mobility depends not only on the vehicles themselves, but also on the reliability, scalability and performance of charging infrastructure.
“Drawing on its expertise in materials science and application engineering, Henkel works alongside OEMs and battery manufacturers from the earliest design stages through validation and testing. Through our global Battery Engineering Centres, combined with advanced modelling, simulation, and virtual adhesive technologies, we help accelerate development, optimize system performance, and reduce time-to-market,” says Natasha.
Comprehensive portfolio
“Henkel supports the performance, safety, and durability of EVs through a comprehensive portfolio of advanced material solutions, including adhesives, sealants, specialty tapes, thermal interface materials, and functional coatings.
“Our technologies also enable circularity through innovations such as debonding-on-demand, helping make battery repair, disassembly, and recycling more efficient.”
