“Innovative solid-state lithium-sulphur battery technologies, aimed at safer, more sustainable mobility”
TECNALIA develops more efficient energy solutions in the European battery innovation ecosystem
TALISSMAN is stepping up cooperation between its partners and making progress on its roadmap to helping to develop more efficient energy solutions, thereby establishing itself as a key player within the European battery innovation ecosystem. This week, representatives gathered at the Fraunhofer IWS institute for their Annual General Meeting, a key event in the development of advanced batteries.
Attendees presented the main results and achievements over the last twelve months, and set out the lines of action that will shape the final phase of the project. The aim of TALISSMAN is to further develop innovative solid-state lithium-sulphur battery technologies, geared towards safer, more sustainable mobility.
The event in Dresden was not limited to a technical review. Members also had the chance to take a tour of the Fraunhofer IWS facilities, where they were able to see cutting-edge battery-related technological capabilities with their own eyes.
TECNALIA’s role
TECNALIA is developing key solutions to ensure that these batteries work reliably and can be manufactured on an industrial scale:
- design of lithium anodes with 3D carbon structures
- development of manufacturing processes that can be scaled up for future prototypes
This work is crucial because one of the biggest challenges related to lithium-sulphur batteries is maintaining their performance over many charge cycles.
Applications
The applications envisaged are sectors where weight and range are critical: electric vehicles, heavy goods transport and electric aviation.
Project goal
The aim of the project is to gradually replace current lithium-ion batteries with lithium-sulphur batteries, which have several key advantages:
- Higher energy density (greater range with less weight).
- The use of plentiful, cheap materials such as sulphur.
- Lower environmental impact and less reliance on critical raw materials.
Researchers are working on two main technological concepts: a quasi-solid-state hybrid battery (target: 2027), and an all-solid-state sulphide-based battery (target: 2030). Both aim to improve safety, reduce the risk of fire and extend the service life of batteries.
Significance for Europe
TALISSMAN also has a strategic objective: to strengthen Europe’s technological independence in the field of batteries and reduce its reliance on imported critical materials, in line with the European Green Deal and the energy transition.
