Summary of the overall project:
The storage of electrical energy is one of the main challenges for the electrification of aviation. Conventional batteries would add a lot of weight and volume to airplanes and thus reducing their performance. Parasitic mass and volume can be reduced by the usage of multifunctional materials. The scope of the project „Structural energy storage focussing on battery cells with load bearing properties“ is the integration of battery materials into fibre reinforced plastics on a small scale. The usually used resin shall be substituted by the battery materials enabling the storage of electrical energy while maintaining mechanical properties.
This project is part of the DFG funded cluster of excellence “SE²A – Sustainable and Energy Efficient Aviation”. Within the cluster new technologies for the sustainable and energy efficient aviation are being developed by a holistic approach.
