For more than 50 years, 3M has served multiple industries with advanced solutions for electrical grounding, EMI shielding and protection from electrostatic discharge. Today we focus this expertise in a broad selection of electrically conductive adhesive transfer tapes (ECATTs), metal foil tapes and metallized fabric shielding tapes for electric vehicle battery systems. Many of these materials are designed specifically to block electromagnetic interference (EMI) across a wide range of frequencies. They perform consistently even in harsh environments. They help you keep your battery components operating as designed, and assist you with your regulatory compliance requirements.
3M grounding and shielding tapes feature pressure-sensitive acrylic and silicone adhesives which serves multiple global markets including electronics and automotive. They are specially engineered with conductive particle fillers for low and stable contact resistance, uniform conductivity and maintaining adhesion in the harsh environments.
3M ECATTs, electrically conductive foil tapes and fabric tapes are suitable for xEV battery module and cooling plate grounding, battery cover grounding and shielding, battery management system (BMS) grounding and shielding and other EV battery applications.
3M provides ECATT, foil tape and fabric tape solutions in a range of thicknesses and adhesion levels for optimal EMI grounding and shielding at specific gap requirements. All solutions feature pressure-sensitive adhesives that deliver excellent wet out and do not require time or equipment for curing.
Based on decades of developing electrically conductive solutions for consumer electronics, industrial and avionics, EMI grounding and shielding tapes from 3M are engineered to withstand a variety of factors – temperature extremes, humidity, shock, vibration and more – that are typical in electric vehicle battery systems. They provide ideal combinations of adhesion and conductivity for the long-term management of EMI/RFI, helping keep EV battery systems functioning without issues throughout the life of the vehicle.
