e-mobility Technology International | Vol 7 | Winter 2020 Cost. Capital expenditure costs of implementing adhesive on a production line vary depending on the level of automation required and sophistication of the equipment. It is possible to use adhesives for minimum outlaye.ghandheld dispensing guns. Overheads will vary according to the amount of space required and cost of running and maintaining equipment. Adhesive products themselves, considering the amount of adhesive used per battery, will come under ongoing cost scrutiny. It is interesting to note, the level of thermally conductive filler and the nature of the filler is the main cost driver for thermally conductive adhesives. Higher levels of thermal conductivity can be achieved with different, more expensive fillers, but dielectric strength can be affected, with materials becoming electrically conductive – for some applications, this is great, but in the case of high voltage batteries for Graph showing how the cost is relational to conductive filler content (metal oxide). electric vehicles, probably not so desirable! Where are adhesives and sealants used? • Encapsulation or potting of battery cells • Bonding cells into modules • Bonding modules to cooling plate / heat sink • Gasketing and sealing the battery pack • Encapsulation and potting of other sensitive electronic components • Potting of connectors and sealing pyrotechnic disconnect units As well as battery bonding, high performance adhesives are also used for electric motor bonding – bonding magnets to rotors, magnets to stators, and sealing motor housing. Motors are often requiring adhesives to withstand 180-220°C as well as rigorous impact and thermal shock testing. In the event of an accident, a pyrotechnic disconnect unit detonates to release the battery system to help prevent fire and electrocution, adhesives are used to secure and pot connectors as well as seal and protect units. Friable adhesives can be used to secure the explosive charge, similar to those found in airbag detonation devices. “ Here at Permabond we have a portfolio of special developments combining high thermal conductivity, fire retardancy, toughening, and also adhesives with high-temperature resistance. We have a long and impressive history of supplying adhesives to the automotive industry worldwide, with many products specified by leading automotive manufacturers and Tier 1 automotive suppliers, who insist on high quality cutting-edge products. Bespoke formulations can be developed to meet our customers exact requirements, helping them to achieve production savings and performance benefits. ” e-mobility Technology International | www.e-motec.net 93
