- Nachwachsende Rohstoffe und neue Technologien
Abstract
The aim of the project is to develop new bio-based components for battery cases. Through a new production technology of battery cells, the storage density is to be improved by at least 10%. Further improvements will be achieved through a lightweight construction concept of cells, modules and cases and through the use of wood hybrid components for the whole battery. Overall, a weight reduction of approx. 30% is to be achieved through the use of bio-based materials. The CO2-footprint can thus be improved by at least 20%. A positive side effect of the weight reduction is that it can increase the range of e-vehicles. Wood has numerous strengths that can be exploited when used as a construction material in a battery: easily calculable and slow burn rates, comparatively low smoke development and emission of toxic gases, low thermal conductivity, very good vibration damping, very high specific stiffness and strength, high impact energy absorption, excellent raw material availability, low material costs, simple and inexpensive machinability and a low ecological footprint. By combining wood and other bio-based materials with conventional components in a battery, favorable structural-mechanical and thermal properties of both materials can be complemented and thus utilized. Besides eco-design and lightweight construction, recycling and 2nd-life-use is the third major contribution to ecologically improved products and components in e-mobility. The batteries or modules should therefore be designed in such a way that they can be easily removed after use and used for a second life cycle in stationary energy storage systems. The aim of the project is to bring the results very close to industrial implementation. This will also make the technical, ecological and economic potential of energy storage systems measurable. In addition, training and recommendations for industry will help to transfer the knowledge quickly and efficiently into the economy.
