Functional Adhesive Tapes How Lohmann is Providing Solutions for the Future of Electric Mobility Despite the challenges faced in establishing a competitive European battery industry, the global EV market is constantly growing. As a proportion of new car registrations, sales of EVs increased from 28% in Q12023 to 41% in Q3-2024. In Europe new EV registrations increased to 56% in Q3-2024 in the top five countries. (Source: Strategy & PWC, Electric Vehicle Sales Review Q3-2024). Positively, and in part driven by government regulation, the market for electric vehicles is forecast to damage – between 15°C to 35°C – the materials and battery pack design has to be selected to enable a stable heat transfer from the cooling system to the battery cells and vice versa. Efficient heat transfer is not only essential for the longevity of battery cells, but also for the other temperaturesensitive components that have to be protected against heat and cold. steadily grow and, according to S&P Global Mobility, by the end of 2025 to account for 20.4% of the total market. However, to increase the speed of EV adoption there remain challenges to overcome such as: range anxiety, improved and reliable charging network, the speed of charging and the safety concerns with regards to battery thermal events. To improve battery performance and speed-of-charging, excellent thermal management is key. Battery packs generate the most heat during rapid charging and highpower discharge events. To keep battery cells within an optimal temperature range, where they take the least Our Battery Team at Lohmann (f. l. t. r.: Phil Lötz, Nicole Ehrmann, Siddhant Srivastava) Distance from heat source [cm] Heat sink

Improving thermal management is a key reason Lohmann developed their new product line – the DuploCOLL TC series. These thermally conductive tapes have been developed on the basis of solventand silicone-free adhesives which meet the latest requirements for thickness (250μm – 2mm), fire stability (UL94-V0) and high electrical insulation. In addition to these „functional“ properties, the pressure sensitive adhesive tapes have exceptionally good wet-out on to different surface structures, thus reducing the thermal resistance between the temperature source, the tape and the temperature sink.
