Development of a functional composite insulation and foam material for battery housings - IsoFoamComp

Project summary

Besides the raw materials used and the large CO2 footprint during production, the risk of battery fire is one of the major drawbacks that discourages many potential users from using battery storage or from switching to this form of energy storage. The goal is to develop a novel composite material consisting of an aluminium foam component and a thermally switchable polymer layer. With this composite material, passive temperature control of the cells and modules is to be realized, this increasing range and service life. In addition, in the event of thermal runaway of one or more cells, an insulation layer is to be formed that protects adjacent cells and modules. The material to be developed will be used mainly in battery applications such as electro mobility and stationary storage but can be applied in other areas where fire safety is relevant. The development contributes to making battery storage safer and more efficient and thus represents a further step towards climate neutrality.
