Avery Dennison Performance Tapes has recently unveiled a new EV Battery Venting Materials Portfolio that aims to enhance safety in electric vehicle (EV) batteries by addressing the risk of thermal runaway. The portfolio includes single- and double-coated anisotropic filmic tapes with proprietary fire-barrier coatings and pressure-sensitive adhesives (PSA) for bonding. These venting solutions are designed to provide a level of flame resistance that can help prevent the spread of flames and hot gases in the event of a fire.
Manufacturers of EV batteries typically implement venting strategies at the cell, module, and pack levels to mitigate the risks associated with thermal runaway. When Avery Dennison’s battery venting tape solutions are applied to module- or pack-level venting holes, they facilitate quick burn-through to enable venting through a channel. The opposite side of the tape offers extended flame resistance to prevent flames and hot gases from spreading to adjacent cells. The flame retardancy of the outer side lasts less than 4 seconds, while the adhesive side lasts longer than 15 seconds, contributing to the overall safety of the battery.
Max Van Raaphorst, Business Development Manager for eMobility, Automotive, and Energy Storage at Avery Dennison Performance Tapes North America, emphasized the unique properties of the new venting solutions. These tapes are engineered to provide differential performance to flame exposure, allowing for the development of effective emergency venting strategies. By combining these venting tapes with other thermal runaway mitigation materials, manufacturers can create efficient and space-saving designs for EV battery packs. The ultimate goal of these solutions is to enhance the safety, efficiency, and ease of assembly of EV battery systems.
In addition to providing flame resistance and facilitating venting, the new venting solutions from Avery Dennison Performance Tapes offer benefits in terms of design flexibility and compatibility. These tapes can be integrated with a wide range of other materials commonly used in thermal management and safety applications for EV batteries. By incorporating these venting tapes into their design processes, manufacturers can enhance the overall performance and safety of EV battery packs, meeting the evolving regulatory and safety standards in the automotive industry.
The introduction of the EV Battery Venting Materials Portfolio by Avery Dennison Performance Tapes signifies a commitment to innovation and continuous improvement in the field of thermal management and safety for EV batteries. With the increasing adoption of electric vehicles worldwide, the demand for reliable and effective solutions to mitigate the risks associated with battery fires and thermal runaway is growing. By providing high-quality venting tapes that offer superior flame resistance and emergency venting capabilities, Avery Dennison aims to support the transition to cleaner and safer mobility solutions.
Overall, the new venting solutions from Avery Dennison Performance Tapes represent a significant advancement in the field of EV battery safety. By offering differential performance to flame exposure and facilitating efficient emergency venting, these tapes can help reduce the risks of thermal runaway and enhance the overall safety and efficiency of EV battery packs. As the automotive industry continues to shift towards electrification, innovative solutions like these are crucial for ensuring the widespread adoption of electric vehicles and advancing the development of sustainable mobility solutions.
