Battery

Batteries can overheat if they are damaged or short-circuited (thermal runaway). This heat can spread quickly and, in extreme cases, lead to fires or explosions. Special adhesive tapes can be used to increase safety and minimise the risk of fire. They help to slow down or prevent the spread of fire by acting as a barrier and delaying the spread of flames between components.

Electrical insulation in vehicle batteries is of enormous importance. On the one hand, to ensure safe vehicle operation and, on the other hand, to keep the range and service life of the battery loss-free. Adhesive tapes offer you safe electrical insulation and at the same time reliable protection against dielectric breakdown.

They are often used to wrap battery cells as well as battery modules. But they are also used to cover cooling plates or metal parts such as module cooling plates, module frame materials and busbars.

Effective heat management – so-called thermal management – is crucial in the battery design of electric vehicles. Only if heat is dissipated and sufficient cooling is achieved can safe use be guaranteed.

To achieve this, flame-retardant adhesive tapes are used that also have a high dielectric strength. They are used, for example, between the cooling plate and the battery module or between heat sinks. Here, in addition to the assembly, they provide a thermal interface between the components and can safely dissipate the heat.

To extend the life of electric vehicle batteries, they must be as robust as possible. This means that shocks, jolts and vibrations, extreme road and weather conditions must not damage the battery.

Here, too, tape can provide support and be used, for example, to seal battery housings so that the battery as well as the cells are protected from penetrating liquids, gases or particles. In addition, tape can help to fix compression pads for battery cells and battery modules or to fill gaps. This protects the battery from impact damage, compensates for vibrations and ensures safe storage.
