Project Background


Research as in LiBAT is a central component of the innovation process in the European Union. The development of a new lightweight HV battery suitable for aviation is addressing a newly arising technological field with a range of potential future applications.

The Clean Sky program is the European approach to address the challenges for the aviation sector that come about with globalization, climate change and scarcity of resources. Clean Sky 2 technologies are expected to cut fuel burn & related CO2 emissions by 20-30%, cut noise levels (compared to 2014) by a similar amount and to significantly improve competitiveness and mobility in Europe.

One central path pursued is the departure from fossil fuels in favor of electric drives and storages with the goal of eco-efficient flying with a drastic reduction of chemical and acoustic emissions. Of great importance here is – in addition to efficiency – the safety aspect with regard to drive components and storage elements. Especially the latter must be reliably secured against failure and hazards.

The integration of new energy and propulsion systems requires new approaches in the infrastructure as well as in the system architecture of the aircraft and thus also offers new possibilities for a holistic increase in efficiency of flight operations.

Potential is maximized once the system architecture design and battery design are considered hand-in-hand. A tailored approach for the design of the battery pack itself – taking the integration into the aircraft system environment into account from the beginning of the development – opens important innovation potentials for weight and cost reduction.

The challenge of the battery pack design is to achieve a reliable, efficient and safe overall battery system solution, optimizing in terms of energy storage capacity, electrical power, total mass and volume, as well as thermal management. The special focus of the LiBAT battery pack lies on light weight together with high energy density and high continuous power.

The consortium has considered a set of possibilities to approach the challenges of the project and distilled an innovative solution, combining some new and some rarely pursued approaches with state-of the art battery technology. The design is especially innovative in the areas of thermal management, the integration of power converting functions, as well as the packaging concept.
