EV battery electrical insulation design guide

Avery Dennison Performance Tapes has released a comprehensive design guide aimed at engineers and decision-makers involved in electric vehicle (EV) battery design and manufacturing. The guide focuses on the use of dielectric tapes, specifically the Volt Tough™ portfolio, as an effective electrical insulation solution within battery packs. These single-sided, filmic pressure-sensitive adhesive tapes combine dielectric films with high-performance adhesives, offering a modern alternative to traditional insulation coatings. The Volt Tough™ tapes provide several advantages critical to contemporary battery pack requirements. Their high dielectric strength allows for thinner insulation layers, which contributes to increased energy density within the pack. Additionally, these tapes enable faster production through instant bonding and offer durability, conformability, and tear resistance, making them well-suited for complex battery geometries and sharp corners. The guide also highlights flame-retardant versions that comply with UL® 94V-0 standards, ensuring safety and regulatory adherence in battery applications. Beyond technical specifications, the design guide aims to assist users in understanding the properties and benefits of Volt Tough™ tapes, helping them make informed decisions when integrating these materials into EV battery designs. It provides practical advice on incorporating the tapes through automation and other manufacturing processes, enhancing efficiency and consistency. Avery Dennison also encourages collaboration with customers to develop customised insulation solutions tailored to specific project needs. The release of this guide coincides with Avery Dennison’s broader educational efforts, including free EV engineering webinars available on demand. These resources support industry professionals in staying updated on innovations in battery insulation technology and best practices for implementation. As EV battery designs continue to evolve, such materials and knowledge-sharing initiatives are poised to play a key role in advancing performance, safety, and manufacturability in the sector.
