Avery Dennison launches Volt ToughTM Electrical Insulation Tapes

January 11, 2024

Avery Dennison Performance Tapes has announced the launch of its Volt Tough portfolio of electrical insulation tape solutions.

This new range of electrically insulative, single-sided filmic tapes is designed to address the insufficient electrical insulation in EV battery packs, a critical aspect in protecting cells and other sensitive components to prevent electrical arcing that can lead to shorting and fires. Electrical arcing can occur between high-voltage battery cells and conductive components throughout a pack, including cooling components, busbars, cell connection systems, heat spreaders, and other structural elements.

The portfolio includes a wide range of tapes that incorporate several critical features for OEMs and converters, including conformable options for curved geometries, high abrasion-resistant options, various color options for vision inspection systems, flame-retardant options for UL® 94 and other flame requirements, high dielectric strength with thin, consistent profiles enabling higher energy density, and instant bonding to enable efficient production.

Compared to EV battery spray coatings, Volt Tough tapes offer several benefits, including lower cost, no curing time, thinner profiles for better heat flow, and extended shelf life.

In addition to the tape selections offered in the Volt Tough portfolio, Avery Dennison provides customized solutions to meet unique needs. These customization options include quick-stick and high-tack adhesive formulations, as well as single-coated foam tapes that improve insulation.

Scott Krusinski, market manager, Energy Storage, Avery Dennison, said, “With every major OEM currently electrifying their fleets, engineers are facing new challenges in dealing with high voltages in their battery packs. The need for safe, reliable, high-performing solutions has never been greater. The Volt Tough portfolio is specifically engineered to enhance electrical insulation in EV battery packs. Proper insulation is critical to protecting cells and other sensitive components to prevent electrical arcing that can lead to shorting and fires.”
