During the Battery Show 2019 in Stuttgart, Henkel will launch new technologies that enable cost-efficient large-scale assembly and lifetime protection of battery architectures. As all major automotive OEMs and new players are rapidly launching new electric vehicle (EV) models, Henkel is leveraging its broad technology base and many years of expertise and experience to drive the transformation from traditional engines to electrified powertrains. Tap into the Henkel know-how and visit the expert team at booth 1025 from May 7 to 9.

Henkel has identified three major challenges for battery manufacturers: cost-efficient processes and technologies allowing high-speed assembly of cells; ensuring reliable thermal management for operational safety and meeting the UL94 flammability standard; and allowing serviceability of battery packs. With a comprehensive range of technologies and deep know-how tailored to solving these new challenges, Henkel has set its mind on becoming the industry’s leading full-solutions partner, supporting its customers from design to integration. Frank Kerstan, Director e-Mobility & Powertrain at Henkel: “We are determined to support our customers with application and process expertise, which we will highlight during the Battery Show in Stuttgart”.

As shown in figure 1, Henkel’s solutions and services are focused on eight integrated key technologies that combine existing with new solutions. Some notable examples include:

Battery assembly adhesives:
Henkel offers multiple adhesives that are especially suitable for large scale assemblies of hundreds and thousands of battery cells by UV curing in less than 15 seconds. Whether the battery design is done with cylindrical, pouch or prismatic cells, Henkel technologies enable these various battery architectures.

Thermal interface materials (TIM) – thermal gap filler and thermal
adhesives:

To ensure safe and efficient thermal management of the battery cells and
modules, Henkel has a broad portfolio of TIM products, including siliconefree
Bergquist Gap Fillers. During the show, Henkel will launch a line of
silicone-free, automation-friendly liquid gap fillers, with the debut product
offering a thermal conductivity of 3.0 W/m-K. Furthermore, Henkel offers
Gap Pad and Sil Pad materials for batteries, as well as thermal adhesive
solutions which provide structural shear strength of >10 MPa, allowing
different coefficients of thermal expansion to be overcome through high
elongation.


Liquid gasketing:
For the protection of the battery packing housing against leakages, Henkel
provides different liquid gasketing technologies that are applied by
automated robot. For serviceability or repair, these technologies also allow
the top cover of the pack to be reopened. An additional benefit stems from
their flame-retardant properties and compliance with UL94.


Loctite high-reliability solder pastes:
Strong, high-integrity electrical interconnects within various control boards
for battery management systems are essential for lifetime functional
reliability. Henkel’s award-winning line of temperature stable, Loctite GC
solder paste materials will be on show, alongside the company’s highreliability
90iSC alloy, designed in cooperation with automotive industry
leaders.

Loctite high temperature-compatible underfill:
Newly-developed Loctite Eccobond UF 1173 device-protecting underfill has
been designed specifically for high operating temperature, high reliability
applications within automotive systems. The material has been formulated
with health and safety top-of-mind; it contains no reportable REACH SVHCs*
(substances of very high concern) and is not CMR classified.


Pre-conference workshop: The “Specifying Thermal Management
Solutions to Optimize Battery Safety and Performance” workshop on May 6
will be moderated by Henkel Asia-Pacific Head of Automotive Electronics &
Global Market Segment Head for e-Mobility, Pankaj Arora, and includes
presentations from numerous industry thought leaders. See the full program and register here:

Live product demonstration: At Henkel booth 1025, Henkel Technical
Service Manager, Nicolas Riem, will show the effectiveness of the new
Bergquist silicone-free liquid Gap Filler TIM, designed for high-throughput
production, low assembly stress and excellent thermal control. Live
demonstrations will take place on May 8 at 13:30.

Backed by strong application know-how, R&D test centres around the world and strong strategic alliances (e.g. with RLE International), Henkel is in the unique position to be a partner for its customers’ engineering teams. As such, the company is driving the future of e-Mobility by enabling the industry to solve its significant electrification challenges and is looking forward to engaging with customers during the event.
