Adhesive tapes Tapes for battery bonding in electric vehicles

Coroplast Tape offers cost-effective, weight- and space-saving solutions for bonding, wrapping, or separating components of EV batteries. In doing so, we help enhance the stability and safety of this key component of electromobility.

Our Approach Diverse solutions for bonding, insulating, and sealing electric vehicle batteries

Coroplast Tape is one of the leading manufacturers of technical adhesive tapes, ISO 9001 and IATF certified, and has been developing adhesive solutions for electric vehicles for over 15 years. With this experience and our extensive range of high-performance adhesive tapes, specialty foams, and films, we create customized products for various requirements in EV battery manufacturing.

Abrasion resistance, high-temperature stability, and dimensional stability: Our adhesive tapes for battery systems offer all the properties that have proven essential and effective in battery bonding. In this way, we help drive electromobility toward a safe and successful future.

Coroplast Tape offers a wide range of adhesive solutions for secure electromobility

Battery Manufacturing Application examples for battery bonding

  • Assembly: Weight- and space-saving bonding of components in the battery pack throughout the vehicle's entire lifespan.
  • Thermal Management: Protective wrapping and sealing of sensitive components to prevent heat spread.
  • Fire Protection: Safe separation and insulation of individual lithium-ion battery cells, e.g., to prevent thermal propagation.
  • Gap filler and spacing solutions: For example, to compensate for cell expansion within the battery housing during the charging process.
  • Cell type: Support for cylindrical and prismatic battery cell types, as well as pouch format.
  • Bondings on a battery with cylindrical cells
    Coroplast Tape offers adhesive solutions with all the essential properties for the integration of cylindrical battery cells.
  • Bondings on a battery with prismatic cells
    Coroplast Tape also offers the right and secure adhesive solution for prismatic battery cells.

Thermal Runaway Avoiding thermal propagation

A long driving range is considered key to customer acceptance of electric vehicles. More powerful lithium-ion batteries are therefore essential. To achieve the required energy density, manufacturers are using an increasing number of battery cells in the same amount of space.

However, this extreme packing density of battery modules also increases the risk of short circuits in individual battery cells. For example, if an unprotected cell ignites, the entire energy storage system overheats (thermal runaway), and the spark can quickly spread to neighboring cells. This creates a chain reaction, also known as thermal propagation. It can lead to a fire that is difficult to extinguish or even an explosion.

Our high-temperature-resistant battery tapes prevent the spread to neighboring cells, providing enhanced safety for battery systems.

High-performance adhesive tapes for battery bonding

Coroplast Tape high-performance adhesive tapes from the 9000 SPT series are often the first choice for safe and cost-effective applications in electric vehicle battery manufacturing due to their versatility. They feature a homogeneous, continuously adhesive, and highly flexible acrylic adhesive mass. As a result, these acrylic foam adhesive tapes are significantly superior to conventional double-sided foam tapes and mechanical joining methods.
