Its most important property is its good thermal conductivity of 1.0 W/(m·K). This means that battery cells can not only be bonded into the battery housing. The heat generated during operation can also be dissipated efficiently. As a result, the adhesive combines structural bonding and thermal management system mounting in one step instead of having to manually fix battery cells and then use gap fillers for heat dissipation. Saving one process step, this adhesive is said to simplify production.
The product specially developed for Bosch is flame-retardant in accordance with the industry standard UL 94 V-0, designed for the entire temperature range of the battery, and offers high strength on battery cells and typical housing materials. Its tensile shear strength on aluminium is 18 N/mm².
According to Delo, the 48 V systems from Bosch are so compact that they allow vehicle manufacturers maximum flexibility during installation. The battery measures 140 millimetres in height. This means it can be placed in discreet places such as the trunk or under the passenger seat. The key to the compact design lies in its thermal design. Bosch has worked with partners to develop particularly robust lithium-ion cells. They even work at temperatures of up to +75 °C. Thanks to their greater heat resistance, a simpler cooling concept is possible.
