Electric Vehicle Battery Safety

Design

As EV battery technologies continue to develop rapidly, the battery design landscape is highly dynamic and fragmented. OEMs require battery safety solutions that integrate well with their current designs, while simultaneously looking for future-oriented solutions for their next-generation designs and subsequent requirements.

 Therefore, as a complete solution provider, we are always working closely and flexibly with our customers to develop and implement tailor-made products and technologies that cater to the wide variety of designs, application needs, and technical requirements that come along across our broad base of global customers.

Processability and automation

With skyrocketing demand projections for EVs, OEMs are looking for battery fire protection solutions that can integrate seamlessly with their manufacturing process and that can be applied in an automated way. 

As a long-time trusted partner to the automotive industry, Henkel understands this and therefore develops innovative solutions designed for automated large-scale production. In addition, our customers benefit from access to Henkel’s process expertise, global presence, and global partner network, taking advantage of technical support and deep guidance on testing, dispensing, and overall process setup.

Sustainability

OEMs and battery manufacturers are on the lookout for fire protection material solutions that would help them achieve their sustainability goals, for example on CO2 emissions and circular economy, and ultimately contribute to a clean and sustainable shift towards zero-emissions mobility.

At Henkel, sustainability has been part of our DNA since our foundation. In recent years, we have been making rapid progress on all fronts, aiming to reach our bold ambition of being climate positive by 2030. In light of that, we are committed to using non-hazardous and environmentally friendly materials in our solutions. In addition, our solutions are optimized for automated applications, leading to savings in energy and waste due to high accuracy and efficiency. Moreover, we ensure that circularity and recyclability are taken into account from the earliest phases of product development.

Fire and heat shielding coatings

Fire and heat shielding coatings are flame retardant materials that can be applied on the inside or the outside of the battery pack lid, providing a highly protective shield against the spread of fire and heat. These coatings from Henkel provide excellent environmental resistance, strong adhesion to multiple substrates, and support automated dispensing through Flat Stream and Spray Coating applications.

Thermal propagation prevention potting

Potting materials provide a protective fire-resistant interface with a defined thermal conductivity. Our potting materials provide suitable viscosity for battery applications, in addition to fast processibility and high automation.

Gasketing

The sealing of the battery pack requires a gasketing material between the battery pack housing and the lid, with the primary aim of protecting the inside of the battery pack against the external environment. In the possible case of a battery thermal runaway, the gasket needs to resist the high temperate and subsequent fire to prevent leakage and spread outside of the battery pack.
