How PSA tapes optimize battery production

The rapid growth of electric vehicle (EV) production has shifted the industry’s focus from proving feasibility to mastering manufacturability, particularly in battery assembly. With over 60 million EVs now on the road globally, manufacturers face the challenge of scaling production while maintaining quality, safety, and cost-effectiveness. One promising approach to meet these demands lies in optimising material choices, especially the use of pressure-sensitive adhesive (PSA) tapes, which can streamline complex battery manufacturing processes. PSA tapes are a versatile and mature technology widely used across automotive and transportation sectors. They offer several advantages over traditional bonding methods such as liquid adhesives and mechanical fasteners, including clean, repeatable application, compatibility with automation, and reduced mass and part count. These tapes can be tailored with various facestocks and adhesives to provide additional functions like electrical insulation, thermal protection, and shock absorption, making them particularly suited to the intricate requirements of battery design. From a manufacturing perspective, PSA tapes contribute significantly to design-for-manufacturability (DFM) by addressing common production pain points such as wasteful steps and damage to fragile components. Their immediate bonding capability eliminates the need for curing times and associated equipment, reducing both complexity and capital expenditure. Products like Avery Dennison’s next-generation Volt Tough™ Stretch tape exemplify these benefits by offering a flexible dielectric insulation solution that can be applied inline and withstand subsequent cutting and stamping without damage, outperforming traditional powder coating methods in efficiency and cost. Automation is another area where PSA tapes excel, supporting various robotic application techniques including pick-and-place, single-pass liner removal, and wide-web lamination. The immediate adhesion and dimensional stability of film-based carriers help prevent misalignment and improve accuracy during high-speed assembly, which is critical in layered battery packs. This stability enhances yield and overall equipment effectiveness, enabling manufacturers to scale production more reliably and with fewer defects. Ultimately, PSA tapes offer battery producers a means to reduce scrap rates and improve quality by protecting delicate materials during assembly. Their adaptability to both product design and manufacturing challenges positions them as a key enabler in the evolving landscape of EV battery production, where efficiency, automation, and precision are paramount. As the industry continues to scale, the strategic use of PSA tapes may become a defining factor in achieving competitive advantage and meeting the growing demand for high-quality electric mobility solutions.
