This advanced offering of electrically insulative, single-sided filmic tapes is engineered to address the challenges of insufficient electrical insulation in EV battery packs.ADPT20 Cell WrappingADPT20 Cell WrappingAvery Dennison

Arcing can occur between high-voltage battery cells and conductive components throughout a pack, including the cooling components, busbars, cell connection systems, heat spreaders, and other structural elements. Cell Connection SystemCell Connection SystemAvery Dennison

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 a multitude of 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. ADPT20 Electrical Insulation - Prismatic CellsADPT20 Electrical Insulation - Prismatic CellsAvery Dennison
