Range, safety and battery life are some of the important destinations in the new frontier for automotive OEM. 3M will help you get there, because we’re going there too. In fact, we put some of our most enduring and successful core technologies – adhesives, electronics, advanced materials and others – into today’s electric vehicle (EV) battery solutions. If you need something to enhance your specific xEV battery application, we’re ready to collaborate for the future. We’ll help you optimize your designs and streamline production, all through a seamless, reliable global network serving virtually every region in the world. Together, we can continually expand the limits of xEV battery performance, now and down the road.
You face broad challenges in xEV battery production and design. 3M provides practical, scalable and efficiency-enhancing solutions.
To help make you make your xEV battery designs successful, 3M employs the science of temperature control. Our lightweight thermal interface materials help dissipate heat and direct it through precise heat-transfer paths. Thermal insulation helps block temperature extremes, helping moderate operating temperatures in harsh environments. Our dielectric fluids help manage and regulate heat transfer in batteries designed for direct contact cooling.
We will work with you to provide efficient, effective thermal management solutions all the way down the line: streamlined processes, faster assembly, and xEV battery systems designed for extended life, range and recharge time.
Explore our broad range of solutions for xEV battery thermal management in pouch, prismatic and cylindrical xEV battery designs.
Suppression and prevention of thermal runaway propagation in xEV batteries requires materials built for flame and high-temperature resistance, dielectric strength, flexibility, and compression and recovery. Our range of materials delivers very robust high-temperature resistance and dielectric strength for protection against thermal runaway fire propagation during and after a thermal runaway event. It includes barrier materials engineered for resistance to flame and electrical isolation failure. These materials are durable enough for use under the lid and thin enough for use between battery cells.
Below you’ll find our most effective solutions for protecting xEV batteries from flame, pressure, particulates and electrical discharge. 3M collaborates with you to ensure the most effective solutions for your battery applications, helping you meet evolving industry regulations for customer safety.
Assembly of xEV batteries is about performance – in efficiency of design and materials, in serviceability during production, and for drivers on the road. 3M bonding and joining solutions include adhesives that deliver semi-structural and structural strength, making them ideal for use with, or in place of, mechanical fasteners. Our battery sealants virtually eliminate time spent cutting and fitting, and 3M attachment tapes are excellent for applications that do not require adhesive cure times.
In addition, 3M provides advanced lightweighting solutions that allows for the use of lighter, smarter substrates. Our friction shims are a quick solution for stronger, more stable battery mounting systems.
3M collaborates with you on your assembly process improvements such as automated application systems for maximum efficiency, productivity, and vehicle life.
Available in multiple chemistries to suit a broad range of xEV battery designs and applications, our two-part structural adhesives incorporate smoothly into your automated processes.
Our tape solutions cure at lower temperatures compared to brazing, and apply cleanly and consistently between substrates to provide a thin insulation layer that helps resist corrosion caused by metal fasteners.
So much of creating functional and reliable xEV batteries depends on containing electrical charge. 3M delivers a complete selection of scientifically engineered solutions. 3M invented the first electrical tape, and today our electrical grade insulating tapes and films are known worldwide. These tapes and films, along with our range of solid epoxy insulating resins, allows you to choose the hardness, flexibility and dielectric strength for your specific designs.
3M provides the technical know-how to help you choose and incorporate solutions for some of the most basic and critical functions of your xEV battery designs. That means adding dielectric breakdown strength to critical xEV battery components. It means fewer tape wraps during assembly. That’s just the start.
3M provides world-class solutions grounded in the science of acoustics. Our expertise in insulation, damping, bonding and cushioning is vital to helping you successfully design xEV batteries and allows us to provide you with solutions to meet the unique challenges of managing noise, vibration and harshness (NVH) in xEV batteries.
Based on decades of developing automotive NVH solutions, we provide technologies for bonding, damping and insulating in very thin spaces. Aearo Technologies LLC, a 3M company, provides high-performance cushioning materials designed specifically for consistent compression force deflection – ideal for helping control swelling of Li-ion battery cells throughout charge cycles and managing noise, vibration and harshness on the road.
Many of our NVH management solutions are suitable for your automated application.
To meet the demands for xEV performance and range, you work to design more power density into every pack. To meet the equally important demand for long battery life, controlling electromagnetic interference has never been more important.
Reliable point-to-point electrical contact, precisely when and where you need it, is key to keeping xEV batteries performing at their peak. 3M provides a wide range of solutions based on decades of combined expertise in adhesives and electronics. Derived from the industry’s first electrical tape - invented by 3M - our grounding and shielding tapes for xEV batteries are available in a variety of metal foil materials and thicknesses to meet specific challenges in grounding, static charge draining and EMI/RFI shielding. 3M will collaborate with you for testing, prototyping and more.
Electrically conductive adhesive transfer tapes, metal foil tapes and metallized fabric shielding tapes deliver precise, reliable grounding and shielding even in harsh xEV battery environments.

Vehicles depend more and more on sensors that are smart, responsive and dependable. Sensors need to inform drivers, read road signs, and talk to each other. They need to stay aware of dangers, obstacles and rapidly changing conditions. 3M science offers next generation materials, cross industry expertise and real world experience to bring proven solutions to your engineering and design challenges.
Magnet and thermally conductive epoxy adhesives. Boron nitride cooling fillers. Specialty electrical powder resins for enhanced insulation to motor components, and friction shims for increased power density without increasing joint or assembly size. These are just a few of the ways 3M can help enhance the design and manufacture of ePowertrains.
