tesa Presents Automated Adhesive Solutions for EV Battery Assembly at Automotive Engineering Exposition 2026 in Japan
tesa, a global leader in adhesive tapes, showcased its advanced adhesive tapes and automated structural sealing solutions specifically designed for electric vehicle (EV) manufacturing at the Automotive Engineering Exposition 2026 held in Yokohama and Nagoya, Japan. This announcement addresses the rapid proliferation of EVs and the consequent sophistication of battery assembly processes, making significant contributions to improving production efficiency and quality.
Integration of Surface Treatment Technology through Collaboration with Japan Plasmatreat
Through a strategic collaboration with Japan Plasmatreat, tesa has developed an innovative solution that further enhances bonding reliability. By combining atmospheric plasma technology with structural adhesives, surface wettability in automotive paint shops and battery assembly lines is significantly improved, leading to enhanced adhesive adhesion. This technology particularly demonstrates its value in bonding dissimilar materials and complex-shaped components that were challenging with conventional surface treatments. Optimizing surface pre-treatment reduces the risk of bonding failures and ensures long-term product reliability.
tesa’s Adhesive Tapes Enhance EV Battery Performance and Safety
The exhibited tesa dielectric and structural adhesive tapes play a critical role in key EV battery components. Specifically, they are used for wrapping prismatic and cylindrical battery cells, providing both electrical insulation between cells and mechanical protection. Furthermore, these adhesive tapes act as waterproof barriers for battery packs, preventing the ingress of moisture and external contaminants, thereby extending battery life and enhancing safety. This solution also contributes to automating the assembly processes of battery modules and packs, reducing manual labor, and consequently lowering manufacturing costs and increasing production capacity. tesa’s technology offers a comprehensive approach to the challenges faced by the EV industry, namely performance improvement, safety assurance, and manufacturing efficiency.
