Aismalibar develop high end thermal interface materials

The electric car revolution needs new battery concepts, offering reliable and safe operation as well as fast and efficient charging. Car manufacturers use different types of battery cells, cylindrical or prismatic and a variety of pack designs and assemblies. However, thermal stress in the cells negatively affects battery charging capacity, safety and longevity.
