Lightweight battery concept based on VESTALITE® S curing agent
High voltage battery housing for more lightweight and cost-effective e-mobility developed by Evonik and partners
Novel SMC-based electric vehicle Battery Concept
The new holistic battery system maintains strength and high voltage performance, but reduces the battery housing weight by ~10% , offering the automotive industry a safer and more energy efficient alternative to the heavier metal-based, or higher priced carbon fiber-reinforced plastics.
Based on our new epoxy SMC – VESTALITE® S curing agent, the lightweight design and production flexibility helps to deliver significant energy savings making the new battery system suitable for use in all vehicle size and classes.
