Battery Adhesive Tapes & Bonding Solutions

Adhesive tapes and bonding solutions are used in battery cells, modules, and packs to bond, seal, insulate, cushion, and integrate functional materials and components. Depending on the application, they can support dielectric insulation, flame resistance, thermal runaway mitigation, controlled venting, gasketing, cell bonding, and the attachment of thermal or structural barrier materials.

Several types of adhesive and bonding solutions are used in battery systems, each suited to different design and manufacturing needs:

• Bonding tapes:
  Used to attach foams, films, thermal barriers, insulation layers, and other components to cells, modules, or pack structures.
• Flame-retardant and dielectric tapes:
  Used where electrical insulation and flame resistance are required, for example near high-voltage components or in thermal propagation mitigation concepts.
• Sealing and gasketing tapes:
  Used to seal battery enclosures or internal features against dust, moisture, and contamination while supporting reliable assembly.
• Venting-support tapes:
  Used in designs where controlled gas release, directional venting, or sealing of venting paths is required.
• Conformable bonding solutions:
  Used in curved, recessed, or otherwise difficult geometries where rigid materials are hard to integrate.

The core functions of these products include adhesion, sealing, insulation, protection, and manufacturability. In addition to joining materials, they can help improve assembly speed, enable compact battery designs, and support safety-critical functions in both normal operation and failure events.
