Adhesive Tapes for EV Batteries

 Lohmann's DuploCOLL product range covers all major functional requirements in Li-Ion battery assembly: thermally conductive tapes (TC) for cooling plate bonding and heat management, electrically conductive tapes (EC) for EMI shielding and grounding, electrically insulating tapes (IS) for high-voltage protection and cell wrapping, as well as PE, PU, EPDM, and acrylic foam tapes for sealing, NVH damping, and cell expansion compensation. All products are available as rolls, spools, or high-precision die-cuts. 

 Yes. Lohmann operates in-house die-cutting equipment - including laser plotters and rotary die-cutting machines - capable of producing customer-specific geometries in low µm tolerances. Our application technology specialists also support the integration of die-cut tape solutions into fully automated pick-and-place processes. 

 Lohmann is certified according to IATF 16949 - the international quality management standard for the automotive supply chain. Our adhesive systems are tested according to OEM and Tier 1 specifications in our in-house laboratories, including thermal cycling, peel, tack, shear, and chemical resistance testing. 

 The DuploCOLL TC range achieves thermal conductivity of up to 2 W/mK, tested according to ASTM D 5470. The tapes are free of solvents, halogens, and silicones, and are available in thickness variants from 140 µm to 2 mm. They fulfil the flame-retardant requirements of UL 94 V-0. 

 Lohmann offers customised flame barrier tape laminates with very low thermal conductivity that prevent heat propagation between cells in the event of thermal runaway. These compressible laminate solutions accommodate cell breathing during charge and discharge cycles, fulfil UL 94 requirements, and are adapted to specific cell chemistries and battery pack designs. 

 Traditional grounding solutions in battery modules rely on mechanical springs, wires, or conductive pastes - all of which add assembly steps, cost, and potential failure points over the lifetime of the vehicle. Lohmann's DuploCOLL® EC range eliminates this complexity: electrically conductive foam and fabric tapes provide isotropic conductivity in all three axes (X, Y, Z), enabling reliable grounding and EMI shielding through a single self-adhesive tape layer. The compressible foam variants continuously compensate for part tolerances and the natural movement of battery components during thermal cycling - maintaining constant electrical contact without mechanical fastening. All EC products are available as high-precision die-cuts for direct integration into automated assembly processes. 

 UV-LUX is Lohmann's next-generation structural bonding technology for applications that require both precise positioning and high final bond strength.  UV-LUX tapes remain repositionable after initial placement and develop their full structural strength only after UV light activation. Once cured, UV-LUX bonds offer high mechanical strength, excellent chemical resistance, and long-term durability under the thermal and vibrational loads typical of EV battery pack environments. Further technical specifications are available on request from our application specialists. 

 Lohmann will be exhibiting at Battery Show Europe 2026 in Stuttgart (Messe Stuttgart), Hall 3, Booth 3-B30, from June 6 to 9, 2026. Use the contact form on this page to book a personal meeting with our battery experts at the show.
