Mimicking the Production Floor: Advanced Robotics and Dispensing
The operational heart of Inside Henkel’s Battery Application Center lies in its state-of-the-art dispensing setup. Chloe Jindra, a senior application engineer at the facility, provided a detailed tour, showcasing the precision and versatility of the equipment. The robot cell is engineered to handle both one-component and two-component cartridge and bulk dispensing, accommodating a wide array of materials including polyurethanes, epoxies, thermals, and silicones—all critical for various battery assembly stages.
Multiple dispense heads are a key feature, allowing the team to effortlessly switch between different material types without requiring a complete rebuilding of the cell. This flexibility is crucial for efficiently testing diverse adhesive and sealant solutions required for complex battery pack designs. The integrated Human-Machine Interface (HMI) tools offer granular control over critical parameters.
“These HMI tools allow us to control certain factors like our flow rates and our pre-pressures as well as our bead size,” Jindra explained. “So that way we make sure we get the perfect bead size for our customer every time.” The ability to precisely manage these factors is paramount in achieving consistent quality and performance in battery manufacturing, where even minor variations can impact structural integrity and thermal management.
Optimising Material Viscosity for Real-World Application
Beyond precision dispensing, the center addresses a fundamental challenge in material application: viscosity management. The pump systems are designed to accommodate various industry-standard container sizes, including German-sized pails (Hobocks), standard pails, and drums. Crucially, all these systems are heated.
This heating capability is vital because many adhesive materials exhibit significantly different behaviors at room temperature compared to the elevated temperatures (typically 40–60 °C) common on production lines. By heating the materials to their operational temperature range within the lab environment, Henkel ensures that tests accurately reflect how the materials will perform during actual manufacturing. This focus on realistic conditions helps in qualifying materials that are robust and reliable under industrial demands.
Furthermore, operators at the center can initiate and sequence dispensing programs directly from the HMI, eliminating the need to physically enter the robot cell during automated operations. A sophisticated safety system intelligently switches between automatic and teach modes, ensuring personnel safety while allowing customers to observe and collaborate on the floor during specific testing phases. This blend of automation and safety reflects the center’s commitment to both efficiency and collaborative innovation.
The Innovation Frontier: De-bonding on Demand for EV Batteries
While bonding battery components securely is a primary engineering challenge, the ability to safely and efficiently de-bond them presents an equally complex, yet increasingly critical, requirement. Matt Boback, Senior Manager of Inside Henkel’s Battery Application Center, emphasized that a growing portion of the facility’s work now centers on developing adhesive joints that can be intentionally reversed.
This focus on ‘de-bonding on demand’ is driven by several key applications: facilitating in-plant rework of manufacturing defects, enabling field service repairs of battery packs, and critically, supporting the end-of-life recycling of EV batteries. As the automotive industry moves towards greater sustainability and circular economy principles, the ability to easily disassemble and recover valuable materials from battery packs is becoming indispensable.
Boback detailed the collaborative approach to this challenge. “We focused in on two main triggers,” he said, referring to the mechanisms used to initiate de-bonding. “These are both either electrical or thermal de-bonding triggers to safely remove and de-bond the assemblies.” The goal is to engineer adhesive systems that can withstand the intense thermal and mechanical stresses of normal battery operation, yet release cleanly and predictably when exposed to a specific, designed stimulus.
Addressing Repairability and Recycling Mandates
The engineering complexity of developing such adhesives is considerable. An adhesive that releases too easily poses a significant reliability and safety risk for battery packs operating under demanding conditions. Conversely, an adhesive that is impossible to de-bond effectively renders the battery pack a single-use assembly. This creates substantial hurdles for compliance with emerging repairability requirements and tightening recycling regulations, particularly in major automotive markets like Europe and North America.
The work undertaken Inside Henkel’s Battery Application Center aims to provide a consistent and safe de-bonding solution, whether for minor production-line adjustments or for entire packs destined for recycling. This proactive development of de-bondable adhesives is not just a technological advancement but a strategic response to global pressures for more sustainable and repair-friendly EV ecosystems, ensuring that battery packs can contribute to a circular economy rather than ending up as complex waste.
From Laboratory to Production Line: Ensuring Consistency at Scale
A persistent challenge in material science and manufacturing is bridging the gap between successful laboratory prototypes and consistent high-volume production. Matt Boback highlighted this as another critical area of focus for the center. “We want to take something that’s in the lab environment and it’s going to go through pilot lines, through production intent volume,” he explained. “We want to have that consistency throughout the process.”
Achieving this consistency means meticulously matching dispensing parameters across different scales of operation. Parameters such as temperatures, application speeds, bead geometry, and pressures must be precisely replicated. This ensures that an adhesive or material qualified and optimized Inside Henkel’s Battery Application Center will perform identically when applied at a high rate on a customer’s actual production floor. The center’s rigorous quality control protocols are meticulously designed around this crucial handoff, providing confidence to manufacturers that their selected solutions will scale effectively.
Driving Product Innovation Through Collaboration
The facility serves not only as a testing ground for customers but also as a vital feedback loop for Henkel’s internal product development teams. Pankaj Arora emphasized that early-stage collaboration with OEMs during the design phase provides invaluable insights. These interactions surface specific performance requirements and application challenges that would not be apparent from standard datasheet requests alone, ranging from the demands of new cell chemistries to the complexities of evolving pack architectures.
“We are able to dial those learnings back into our development cycles and produce a better product,” Arora stated. This iterative process allows Henkel to continually refine and innovate its adhesive and material solutions, tailoring them precisely to the dynamic needs of the EV industry. The center also leverages advanced digital twin modeling, which simulates physical processes virtually. This significantly reduces the need for multiple physical iteration cycles, thereby accelerating development timelines and optimizing resource utilization.
By fostering a synergistic environment where customer needs directly influence product innovation, Inside Henkel’s Battery Application Center stands as a pivotal hub for advancing EV battery engineering. Its unique blend of production-ready testing, collaborative development, and focus on both robust bonding and reversible de-bonding positions it at the forefront of sustainable and efficient electric vehicle manufacturing.
