Our project CoCoBatt – Innovative solutions for solid-state batteries

Source: FAPS

On March 18, 2025, the CoCoBatt research project was launched under the leadership of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Department of Factory Automation and Production Systems (FAPS) in collaboration with Fraunhofer IKTS.

We are pleased to be part of the project committee that is supporting CoCoBatt throughout the project.

Our contribution lies in the provision of expertise in the field of technical ceramics, in particular the application of NaSICON ceramics as a solid electrolyte in novel battery concepts.

At the heart of this - already award-winning - project is an atmospheric plasma spraying process (APS).

By applying plasma-sprayed copper current collectors directly to ceramic solid electrolytes, the interfacial contact can be significantly improved - a decisive factor for the performance, safety and service life of anode-free solid-state batteries.

Advantages of the process at a glance:

• Improved interface contact with simultaneous non-destructive processing

• Higher volumetric energy density, e.g. for longer ranges in mobile applications

• Reduced charging times thanks to optimised ion conductivity

• Resource-saving and scalable production under ambient conditions

• Prospects for sodium-based battery systems - a sustainable alternative to lithium-based technologies

The CoCoBatt research project makes an important contribution to the development of efficient, ecological energy storage solutions and is one more step towards a sustainable energy future.

We are delighted to be part of this exciting project.
