Avery Dennison Performance Tapes announced the launch of the newly developed Volt Tough portfolio of electrical insulation tape solutions. This advanced offering of electrically insulative, single-sided film tapes is engineered to address the challenges of insufficient electrical insulation in EV battery packs.
Volt Tough can be used for various applications, including battery cell wrapping, cell connections, the cell busbar, as well as for the cooling plate and ribbon.
“With every major OEM currently electrifying their fleets, engineers are facing new challenges in dealing with high voltages in their battery packs,” said Scott Krusinski, market manager, Energy Storage, Avery Dennison. “The need for safe, reliable, high-performing solutions has never been greater.”
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 Volt Tough portfolio is specifically engineered to enhance electrical insulation in EV battery packs,” added Krusinski. “Proper insulation is critical to protecting cells and other sensitive components to prevent electrical arcing that can lead to shorting and fires.”
The Volt Tough 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
- Instant bonding to enable efficient production In comparison to EV battery spray coatings.
Volt Tough tapes provide several benefits that render it a more advanced solution. These include lower cost, no curing time, thinner profiles for better heat flow and extended shelf life. In addition to these tape selections, Avery Dennison offers customized solutions to match unique needs. Customization options include quick-stick and high-tack adhesive formulations, in addition to single-coated foam tapes that improve insulation.
